U.S.-Bulgaria Cooperative Research on Contemporary Issues inNuclear Structure Theory

巴托尔研究所的斯图尔特·皮特尔博士、乔纳森·恩格尔博士、罗兰·拉尔森先生与保加利亚核研究所的彼得·拉切夫博士、鲁西·鲁塞夫博士、安娜·格奥尔基耶娃博士、马里奥·斯托伊佐夫博士、莉莉亚·马里奥娃博士、鲍里斯拉夫·斯拉沃夫博士、韦斯林·迪米特罗夫博士、特塞萨·丹科娃博士、尼古拉·明科夫博士之间的这一美国-保加利亚研究项目；能源(INRNE)和保加利亚索非亚大学将集中讨论“核结构理论中的当代问题”。研究人员将(1)开发用于有限核的夸克描述的映射方法；(2)使用索非亚开发的一些新的多体方法来研究73Ge星系暗物质的探测。保加利亚人对奇质量核的新方法在未来的研究中应该会被证明是有用的。理解星系和整个宇宙中的暗物质是当代物理学面临的最大挑战之一。一项巨大的实验工作正在进行中，目的是使用地面探测器，特别是73Ge探测器来搜索银河系暗物质。这个理论物理项目通过使保加利亚和美国的顶尖专家能够将互补的人才结合在一起，并在彼此感兴趣和有能力的领域汇集资源，从而实现了促进科学知识的计划目标。

This U.S.-Bulgaria research project between Dr. Stuart Pittel, Dr. Jonathan Engel, Mr. Roland Larsson, of the Bartol Research Institute, and Dr. Peter Raichev, Dr. Roussy Roussev, Dr. Ana Georgieva, Dr. Mario Stoitsov, Dr. Lilia Mariova, Dr. Borislav Slavov, Dr. Vessilin Dimitrov, Tsetsa Dankova, Nikolai Minkov, of the Bulgarian Institute for Nuclear Research & Energy (INRNE) and Sofia University in Bulgaria, will focus on "Contemporary Issues in Nuclear Structure Theory." The researchers will (1) develop mapping methods to use in quark descriptions of finite nuclei; and (2) use some new many-body methods developed in Sofia to study galactic dark matter detection by 73Ge. Access to the Bulgarians' new approach to odd-mass nuclei should prove useful in future studies. Understanding the dark matter in galaxies and in the universe as a whole represents one of the greatest challenges facing contemporary physics. An enormous experimental effort is underway to search for galactic dark matter with terrestrial detectors and in particular with a 73Ge detector. %%% This project in theoretical physics fulfills the program objective of advancing scientific knowledge by enabling leading experts in Bulgaria and the United States to combine complementary talents and pool resources in areas of strong mutual interest and competence.
