This thesis is a description of some experiments designed to test the feasibility of doing a detailed study of the specific heat of helium adsorbed in 13X-zeolite, an alumina-silicate with a regular cavity structure. The interest in this system arose from the controversy as to whether the first layer of adsorbed helium is solid or not. It was also hoped that this system would test the postulate(11) that helium is a quantum liquid if experiments were carried out with both helium three and helium four. The experiments reported here, however, were strictly of a preliminary nature and had only the following objectives: to develop some of the techniques, using helium four, necessary for doing a detailed examination of both the helium-four-and helium-three-zeolite systems, to measure an isotherm of helium four adsorbed in 13X-zeolite, and to obtain an estimate of the specific heat of helium four in the 13X lattice at liquid-helium temperatures above 1.8°K. In view of these objectives three isotherms of helium four adsorbed in zeolite were done. These measurements showed that most of the gas was adsorbed at pressures lower than those measured on the manometers. In addition, two heat-capacity runs were done in the temperature region 1.8 - 4.1°K with a bomb calorimeter in the first run the calorimeter was filled with helium; in the second it was empty. The specific heat of helium four in zeolite was obtained by subtracting the results of the second run from that of the first. From this experiment the specific heat of helium adsorbed in 13X is significantly lower than that of the bulk liquid. No specific-heat maximum was observed but this is not surprising when the temperatures used and the manner in which the experiments were done are considered. The preliminary study shows that the study of the helium - 13X system was worthwhile and should be continued in greater detail. Another group has already reported results for helium three in the zeolite (22).

The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.
