Studies of Nuclear Reactions and Structure

佛罗里达州立大学核研究实验室将运行一个串联范德格拉夫加速器和超导直线加速器，用于低能核结构的研究。利用新的康普顿抑制伽马射线探测器阵列研究高自旋核的结构，以探索单粒子和集体自由度之间的关系，包括超变形。反应中的自旋依赖效应将使用由激光泵浦离子源产生的极化离子进行研究。高自旋和高激发态将通过共振粒子衰变光谱进行研究。集体八极态和具有永久八极形变的原子核将在中重核区进行研究。将为这项工作开发适当的仪器，包括超导转换电子光谱仪。不完全聚变对重离子诱导裂变反应的影响也将使用布拉格曲线谱仪来确定电荷态。将会对放射性光束的能力进行规划。一些使用专门的国家设施的低能量研究也将继续进行：在阿贡的APEX探测器和伯克利的GAMMASPHERE设施。包括CEBAF和RHIC在内的其他一些实验室将继续进行高能核研究。

The Florida State University Nuclear Research Laboratory will operate a tandem van de Graaff accelerator and superconducting linac booster accelerator for low energy nuclear structure studies. The structure of nuclei at high spin will be studied with a new array of Compton-suppressed gamma ray detectors to explore the relation between single- particle and collective degrees of freedom, including superdeformation. Spin dependent effects in reactions will be studied using polarized ions made possible by a laser-pumped ion source. High spin and high excitation energy states will be studied via resonant particle decay spectroscopy. Collective octupole states and nuclei with permanent octupole deformation will be studied in the medium to heavy nuclei region. Appropriate instrumentation will be developed for this work, including a superconducting conversion electron spectrometer. The effects of incomplete fusion on heavy ion induced fission reactions will also be studied using a Bragg curve spectrometer to identify charge states. Planning will occur for a radioactive beam capability. Some low energy studies using specialized national facilities will also continue: at Argonne's APEX detector and at the GAMMASPHERE facility at Berkeley. High energy nuclear research will continue at a number of other labs including CEBAF and RHIC.
