He-6与质子散射的微观光学势

Microscopic Optical Potentials for Helium-6 Scattering off Protons

Ch. Elster, A. Orazbayev, S. P. Weppner

摘要:

用微观折叠光学势计算了$^6$ He与质子靶弹性散射的微分截面和分析本领,其中$^6$ He核被描述为在价p壳层中有两个附加中子的$^4$ He核.与以前的工作的性质相反,所有的贡献从价中子与靶质子的相互作用被考虑在内。

英文摘要:

The differential cross section and the analyzing power are calculated for elastic scattering of $^6$He from a proton target using a microscopic folding optical potential, in which the $^6$He nucleus is described in terms of a $^4$He-core with two additional neutrons in the valence p-shell. In contrast to previous work of that nature, all contributions from the interaction of the valence neutrons with the target protons are taken into account.
