Research in Nuclear Physics and its Application to Astrophysics

点击翻译按钮获取中文摘要

This grant supports a program of research in nuclear physics and astrophysics at the Kellogg Radiation Laboratory of The California Institute of Technology. The research is carried out by a group consisting of 6 professional faculty, 2 research faculty, 14 postdoctoral fellows and visiting scientists, 12 graduate students and 8 undergraduates. The research consists of low energy experiments, intermediate energy experiments, and theory. The low energy work includes measurements relevant to the synthesis of the elements in the easily universe and in stellar evolution, and is conducted with accelerators in the Kellogg Laboratory. The intermediate energy experiments employ electron- scattering to probe short-range properties of nuclei. This work will include experiments with an optically pumped polarized 3He target built by the group, to determine the electric form factor of the neutron. The measurements will be made at the Stanford Linear Accelerator Center, at the MIT Bates Laboratory, and at other international accelerator centers. In addition, a search for neutrino-oscillations will continue, using the neutrino beam from the Los Alamos Meson Facility. The theory component of the Kellogg program addresses a variety of theoretical and phenomenological studies, many of which are related to experiments carried out by the Kellogg group. Particular emphasis is placed in all these activities on providing students with the broadcast possible education in nuclear physics.
