RUI: Heavy-Ion Reaction Studies at Hope College

9509900 DEYOUNG这个建议的主旨是研究核物质的行为，因为它使用重离子碰撞的工具从正常的冷条件移动到高度激发的条件。 具体来说，我们建议测量：轻带电粒子符合中间质量碎片（IMF），以确定在较高的能量，角分布的IMF符合在一个范围内的能量，中子-中子相关测量在较低的能量的重残留物的时间尺度，并在中间能量的预平衡轻粒子和重产品之间的重合。我们还建议继续致力于RHIC的星星合作的触发算法和模拟的发展。 除了我们自己雄心勃勃的实验计划，我们还将支持其他人提出的合作effopts，如预期的测量复合系统中粒子发射的自旋依赖性，对不分裂的高激发系统的研究以及对分裂的激发核的额外测量。 来自霍普学院的本科生将参与这些拟议实验的各个方面，并将被收录在最终的出版物中。

9509900 DEYOUNG The general thrust of this proposal will be to examine the behavior of nuclear matter as one moves from normal cold conditions to highly excited conditions using the tool of heavy- ion collisions. Specifically we propose to measure: light charged particle coincidences with intermediate mass fragments (IMFs) to determine timescales at higher energies, angular distributions of IMFs in coincidence with a heavy residue over a range of energies, neutron-neutron correlation measurements at lower energies, and coincidences between pre-equilibrium light particles and heavy products at intermediate energies. We also propose to continue a small effort directed towards development of trigger algorithms and simulations for the STAR collaboration at RHIC. In addition to our own ambitious experimental program, we will also support collaborative effopts proposed by others, such as the anticipated measurements of the spin dependence of particle emission from compound systems, investigations of highly excited systems that do not fragment and additional measurements of excited nuclei which do disintegrate. Undergraduate students from Hope College will be involved in all aspects of these proposed experiments, and included on the publications that will result.***
