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.

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 博士共同开展的这个美国-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。 对于低射弹能量，冷却的主要模式是神经元发射，但偶尔也会发射碎片。 在这些区域的冷却过程中，这些碎片的动能谱和内部激发能的分布都会发生变化。 研究人员计划使用共线中子碎片符合技术收集有关内能对动能依赖性的实验信息，作为测试去激励模型的手段。 该核物理项目通过使美国和东欧的领先专家能够在共同感兴趣和能力强的领域结合互补人才和汇集资源，实现了推进科学知识的计划目标。
