This grant supports research on the properties of nuclei near A=100 amu. These nuclei are neither spherical nor strongly deformed, and have proven difficult to describe using conventional nuclear structure models. New techniques developed by the grantees will be used to populate and measure the properties of low-lying non-yrast levels in a sequence of transitional odd-A nuclei, and the results examined for evidence of rotational multiplets. The latter have been predicted using new models based on persistent rotational degrees of freedom.

这笔赠款支持对A=100 Amu附近原子核性质的研究。这些原子核既不是球形的，也不是强烈变形的，已经被证明很难用传统的核结构模型来描述。受赠者开发的新技术将用于填充和测量过渡奇A核序列中低位非yrast能级的性质，并检查结果以寻找旋转多重态的证据。后者已经使用基于持续旋转自由度的新模型进行了预测。
