The primary purpose of this U.S.-Bulgaria research project between Dr. Todor Stanev of the University of Delaware and Dr. H. P. Vankov of the Bulgarian Institute for Nuclear Research and Nuclear Energy is to study electromagnetic shower behavior. These showers or cascades accompany the production, propagation and detection of high-energy particle signals from astrophysical sources. Joint research efforts will concentrate on defining shower properties by observing differences between hadronic and photonic showers. Results are expected to provide details on energy dissipation and may prove useful in identification and analysis of these high- energy signals in relation to the origin of cosmic radiation. This project in elementary particle physics fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.

美国-保加利亚研究项目由特拉华大学的Todor Stanev博士和保加利亚核研究与核能研究所的H. P. Vankov博士共同开展，主要目的是研究电磁雨的行为。这些阵雨或级联伴随着来自天体物理源的高能粒子信号的产生、传播和探测。联合研究工作将集中在通过观察强子和光子阵雨之间的差异来定义阵雨的特性。结果有望提供能量耗散的细节，并可能证明对这些与宇宙辐射起源有关的高能信号的识别和分析是有用的。这个基本粒子物理项目通过使美国和东欧的专家在共同感兴趣和能力强的领域结合互补的人才和集中研究资源，实现了推进科学知识的计划目标。
