RUI: Heavy-Ion Reaction Studies at Hope College

[00:99 . 00]这个提议的主要目的是利用重离子碰撞的工具来研究核物质从正常的冷态到高激发态时的行为。具体来说，我们建议测量：轻带电粒子与中间质量碎片（IMFs）的重合以确定高能量下的时间尺度，在一定能量范围内与重残留物重合的IMFs的角分布，较低能量下的中子-中子相关测量，以及平衡前轻粒子与中间能量下的重产物之间的重合。我们还建议继续为RHIC的STAR合作开发触发算法和模拟。除了我们自己雄心勃勃的实验计划之外，我们还将支持其他人提出的合作成果，例如对复合系统中粒子发射的自旋依赖性的预期测量，对不碎裂的高激发系统的研究以及对分解的激发核的额外测量。霍普学院的本科生将参与这些拟议实验的各个方面，并包括在将产生的出版物中

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.***
