摘要:

用固体极化质子靶在0.1T的低磁场中测量了71 MeV/核子质子与~ 8He弹性散射的矢量分析本领。从唯象光学模型分析得到的自旋-轨道势被发现是显着更浅,更扩散比全球系统的稳定核,这是一个迹象表明,自旋-轨道势修改散射涉及富中子核。物质半径和自旋轨道势的均方根半径之间的密切相似性也被确定。

英文摘要:

Vector analyzing powers for proton elastic scattering from 8He at 71 MeV/nucleon have been measured using a solid polarized proton target operated in a low magnetic field of 0.1 T. The spin-orbit potential obtained from a phenomenological optical model analysis is found to be significantly shallower and more diffuse than the global systematics of stable nuclei, which is an indication that the spin-orbit potential is modified for scattering involving neutron-rich nuclei. A close similarity between the matter radius and the root-mean-square radius of the spin-orbit potential is also identified.
