Research in Nuclear Physics and its Application to Astrophysics

该基金支持加州理工学院凯洛格辐射实验室的核物理和天体物理研究项目。本研究由6个专业学院、2个研究学院、14名博士后和访问学者、12名研究生和8名本科生组成。研究包括低能实验、中能实验和理论。低能工作包括与宇宙中元素合成和恒星演化有关的测量，并在凯洛格实验室用加速器进行。中能实验采用电子散射来探测原子核的短程性质。这项工作将包括用该小组建造的光泵极化3He靶进行实验，以确定中子的电形状因子。测量将在斯坦福直线加速器中心、麻省理工学院贝茨实验室和其他国际加速器中心进行。此外，利用来自洛斯阿拉莫斯介子设施的中微子束，对中微子振荡的搜索将继续进行。凯洛格计划的理论组成部分涉及各种理论和现象学研究，其中许多与凯洛格集团进行的实验有关。所有这些活动都特别强调向学生提供核物理学方面的广泛教育。

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.
