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

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博士开展的这项美国-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，主要的冷却方式是神经元发射，但偶尔也会发射碎片。在冷却过程中，这些碎片的动能谱和内部激发能分布都发生了变化。使用共线中子碎片符合技术，研究人员计划收集关于内能与动能关系的实验信息，作为测试去激发模型的一种手段。这个核物理项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在相互感兴趣和能力很强的领域汇集资源，从而实现了促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.
