9514157 Balamuth A study of the structure of nuclei with unusual neutron to proton ratios, "halo" nuclei, will be undertaken, Some of these nuclei are thought to be important in stellar evolution but can be produced in high energy heavy ion collisions at the Michigan State University National Superconducting Cyclotron Laboratory. Some neutron-rich light nuclei are produced at sufficient excitation that they decay by particle emission. Their structure and lifetime for dissociation can be inferred by using charged particle, neutron, and gamma ray detectors to measure the break- up fragments. Another category of nucleus of interest includes those nuclei with N=Z. Charged-particle, neutron and gamma ray detectors at Gammasphere (LBL) will be used to provide structure and lifetime information about these proton-rich nuclei. ***

9514157 Balamuth将对具有不寻常的中子质子比的核结构进行研究，“晕”核，其中一些核被认为在恒星演化中很重要，但可以在密歇根州立大学国家超导回旋加速器实验室的高能重离子碰撞中产生。 一些富含中子的轻核在足够的激发下产生，它们通过粒子发射而衰变。 它们的结构和解离寿命可以通过使用带电粒子、中子和伽马射线探测器测量碎裂碎片来推断。 另一类感兴趣的核包括N=Z的那些核。 伽马射线探测器（LBL）的带电粒子、中子和伽马射线探测器将用于提供有关这些富质子核的结构和寿命信息。 ***
