This award will support collaborative research between Professor Abraham Klein of the University of Pennsylvania, Philadelphia, and Dr. G. Do Dang of the Laboratory of Theoretical Physics and High Energies, University of Paris (South). They will examine applications of a new theory of large amplitude collective motion, which may account for certain forms of collective rotational or vibrational motion in atomic nuclei. The two researchers have been working since 1984 on this new theory, which is a development in quantum-mechanical terms of the classical Hartree-Fock formulation. The Wigner transform is used to make the required quantum transformations. Following the development of the new theory, its applicability to systems of practical importance will be examined. This award provides the opportunity for Professor Klein and Dr. Do Dang to apply the theory to the description of large deviations from ground-state equilibrium configurations, well described by classical Hartree-Fock models. This research could lead to increased understanding of large-amplitude problems in classical mechanics, and of certain problems in both fission and fusion reactions.

该奖项将支持宾夕法尼亚大学，费城的亚伯拉罕·克莱因教授与巴黎大学理论物理学和高能实验室的G. do Dang博士之间的合作研究。 他们将检查大幅度集体运动的新理论的应用，该理论可能解释了原子核中某些形式的集体旋转或振动运动。 自1984年以来，两位研究人员就一直在研究这种新理论，这是经典Hartree-fock配方的量子力学术语的发展。 Wigner变换用于进行所需的量子变换。 随着新理论的发展，将研究其对实际重要性系统的适用性。 该奖项为Klein教授和Do Dang博士提供了机会，将理论应用于对基地平衡配置的大偏差的描述，这是经典Hartree-Fock模型很好地描述的。 这项研究可能导致人们对经典力学中的大振幅问题以及裂变和融合反应中的某些问题的了解增加。
