This grant is for support of a program of research in theory and phenomenology of nuclear structure physics. The theoretical research is focussed on developing the most realistic possible shell-model wave functions for nuclear states and on applying the results of these calculations to the analysis of a wide variety of experimental data. The phenomenological studies are directed towards medium-energy reactions with electrons, pions and protons which give new and unique insights into nuclear structure Essentially all regions of the periodic table susceptible to the shell-model approach are encompassed in the program. Topics of special interest include the distributions and sums of Gamow- Teller and magnetic dipole strength, the form factors of magnetic and electric electron scattering, properties of nuclei far from stability, and systematic effects in the properties of the operators for weak and electromagnetic transitions.

本基金资助核结构物理理论与现象学研究项目。理论研究的重点是发展最真实的核态壳模型波函数，并将这些计算结果应用于各种实验数据的分析。现象学研究的方向是与电子，介子和质子的中能量反应，这为核结构提供了新的和独特的见解。基本上，周期表中所有易受壳模型方法影响的区域都包含在程序中。特别感兴趣的主题包括伽莫夫-泰勒和磁偶极子强度的分布和总和，磁和电子散射的形式因素，远离稳定的核的性质，以及弱跃迁和电磁跃迁算子性质的系统效应。
