This thesis describes a novel and robust way of deriving a Hamiltonian of the interacting boson model based on microscopic nuclear energy density functional theory. Based on the fact that the multi-nucleon induced surface deformation of finite nucleus can be simulated by effective boson degrees of freedom, observables in the intrinsic frame, obtained from self-consistent mean-field method with a microscopic energy density functional, are mapped onto the boson analog. Thereby, the excitation spectra and the transition rates for the relevant collective states having good symmetry quantum numbers are calculated by the subsequent diagonalization of the mapped boson Hamiltonian. Because the density functional approach gives an accurate global description of nuclear bulk properties, the interacting boson model is derived for various situations of nuclear shape phenomena, including those of the exotic nuclei investigated at rare-isotope beam facilities around the world. This work provides, for the first time, crucial pieces of information about how the interacting boson model is justified and derived from nucleon degrees of freedom in a comprehensive manner.

This thesis explores two distinct applications of laser spectroscopy: the study of nuclear ground state properties, and element selective radioactive ion beam production. It also presents the methods and results of an investigation into isotope shifts in the mercury isotopic chain. These Resonance Ionization Laser Ion Source (RILIS) developments are detailed, together with an RILIS ionization scheme that allowed laser ionized ion beams of chromium, germanium, radium and tellurium to be generated at the Isotope Mass Separator On-Line (ISOLDE) facility. A combination of laser spectroscopy with decay spectroscopy and mass spectrometry unambiguously demonstrated a cessation of the extreme shape staggering first observed in the 1970s and revealed the characteristic kink at the crossing of the N=126 shell closure. A series of RILIS developments were required to facilitate this experiment, including mercury “ionization scheme” development and the coupling of the RILIS with an arc discharge ion source. Laser spectroscopy has since become a powerful tool for nuclear physics and the Resonance Ionization Laser Ion Source (RILIS), of the ISOLDE facility at CERN, is a prime example. Highlighting important advances in this field, the thesis offers a unique and revealing resource.

This memorial volume is dedicated to physicist Gerald E Brown (1926-2013) or 'Gerry' as he was known to his many students, postdocs, colleagues and friends. As written by one of the contributors to this book, 'Gerry was an inspiring father figure for generations of theoretical nuclear physicists and a great human being'.This book covers a wide range of topics in nuclear physics, including nuclear structure, two- and three-body nuclear forces, strangeness nuclear physics, chiral symmetry, hadrons in dense medium, hidden local symmetry, heavy quark symmetry, cosmic neutrinos, nuclear double-beta decay, neutron stars, gravitational waves, renormalization group methods, exotic nuclei, electron ion collider (EIC), and much more. Most of the authors are Gerry's former students and collaborators.We hope readers will find this book very interesting not only for its physics content but also for the window it gives into Gerry's personal legacy and humanity. This book has vivid recollections of Gerry at Stony Brook, Princeton and Copenhagen, together with his humor and his very special intuitive way of thinking.

As a complex self-bound quantum many-body system, atomic nuclei exhibit various shapes due to significant long-range multipole-multipole interactions among nucleons. Studies of these shapes and the associated nuclear moments have deepened our understanding of simple patterns in complex nuclear systems and are connected to fundamental questions in particle physics, astrophysics, and beyond. In recent decades, advancements in global facilities and detectors have led to increased attention on the study of reflection asymmetry in atomic nuclei, both experimentally and theoretically.The collection of research and review articles presented in this book offers a detailed account of various sub-topics, including reflection asymmetric shapes, nuclear shape phase transitions, nuclear masses, nuclear fission, clustering structures, high-spin states, octupole collective motions, electric dipole moments, and CP violation. These contributions not only highlight the progress made thus far but also pave the way for future investigations. The book will be particularly useful for researchers in nuclear physics.

Quantal density functional theory (Q-DFT) is a new local effective potential energy theory of the electronic structure of matter. It is a description in terms of classical fields that pervade all space, and their quantal sources. The fields, which are explicitly defined, are separately representative of the many-body electron correlations present in such a description, namely, those due to the Pauli exclusion principle, Coulomb repulsion, correlation-kinetic, and correlation-current-density effects. The book further describes Schrödinger theory from the new perspective of fields and quantal sources. It also explains the physics underlying the functionals and functional derivatives of traditional DFT.

Medium heavy nuclei with mass number A=60-90 exhibit a variety of complex collective properties, provide a laboratory for double beta decay studies, and are a region of all heavy N=Z nuclei. This book discusses these three aspects of nuclear structure using Deformed Shell Model and the Spin-Isospin Invariant Interacting Boson Model naturally generated by fermionic SO(8) symmetry. Using these two models, the book describes properties of medium heavy nuclei with mass number A=60-90. It provides a good reference for future nuclear structure experiments using radioactive ion beam (RIB) facilities. Various results obtained by the authors and other research groups are also explained in this book.

This book presents in full the work of the Italian theoretical physicist Ettore Majorana and explains its impacts, which are still being felt. It opens with a contribution by A. Zichichi that considers in depth the scientific genius of Majorana. This introductory chapter is followed, in chronological order, by the eleven scientific papers by this great scientist, in most cases translated into English for the first time. Each paper is accompanied by a comment from an expert in the field in question. Although very few in number, Majorana's papers constitute a heritage of undeniable value and extraordinary scientific meaning, since they laid the foundations for research fields that remain topical today. With this in mind, two additional contributions on ongoing developments in these research fields are included: one on neutrino physics and the other on Majorana fermions in condensed matter. The volume closes with a note on Majorana's life until his ill-fated disappearance.

In my original proposal to Springer for a book on Quantal Density Functional Theory, I had envisaged one that was as complete in its presentation as possible, describing the basic theory as well as the approximation methods and a host of applications. However,after workingon the bookforabout ?ve years, I realizedthat the goal was too ambitious, and that I would be writing for another ?ve years for it to be achieved. Fortunately,there was a natural breakin the material, and I proposed to my editor, Dr. Claus Ascheron, that we split the book into two components: the ?rst on the basic theoretical framework, and the second on approximation methods and applications. Dr. Ascheron consented, and I am thankful to him for agreeing to do so. Hence, we published Quantal Density Functional Theory in 2004, and are now publishing Quantal Density Functional Theory II: Approximation Methods and Applications. One signi?cant advantage of this, as it turns out, is that I have been able to incorporate in each volume the most recent understandings available. This volume, like the earlier one, is aimed at advanced undergraduates in physics and chemistry, graduate students and researchers in the ?eld. It is written in the same pedagogical style with details of all proofs and numerous ?gures provided to explain the physics. The book is independent of the ?rst volume and stands on its own. However, proofs given in the ?rst volume are not repeated here.
