US-Hungary Physics Research on Neutron Emission in Nucleus- Nucleus Collisions

这个由密歇根州立大学的Aaron Galonsky博士和匈牙利布达佩斯中央物理研究所的Ferenc Deak博士合作的美国-匈牙利物理研究项目的主要目标是研究产生热区的核-核碰撞。对于低能量的弹丸，主要的冷却方式是发射神经元，但偶尔也会发射碎片。在这些区域的冷却过程中，碎片的动能谱和内部激发能的分布都发生了变化。利用共线中子碎片重合技术，研究人员计划收集内能对动能依赖的实验信息，作为测试去激发模型的一种手段。该核物理项目通过使美国和东欧的领先专家在共同感兴趣和能力强的领域结合互补的人才和汇集资源，实现了推进科学知识的计划目标。

The primary objective of this US-Hungary physics research project between Dr. Aaron Galonsky of Michigan State University and Dr. Ferenc Deak of the Central Physics Institute, Budapest, Hungary, is to study nucleus-nucleus collisions which produce hot zones. For low projectile energies the dominant mode of cooling is neuron emission, but fragments are occasionally emitted too. During the cooling of these zones, changes occur in both the kinetic energy spectra and the distribution of internal excitation energy of such fragments. Using a colinear neutron- fragment coincidence technique, the researchers plan to collect experimental information on the dependence of internal energy on kinetic energy as a means of testing de-excitation models. This project in nuclear physics fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interest and competence.
