摘要
在KMT多重散射理论框架下,应用动量空间一级光学势,基于Franco和Yin关于核子-核子散射振幅的相随动量转移而改变的建议,研究了入射能量为1GeV时的质子-4He弹性散射.发现这个相改变使得KMT类型的理论计算的微分散射截面和极化本领与实验符合得更好.
This paper is based on a suggestion by Franco and Yin that the phase of the nucleon-nucleon scattering amplitude should vary with momentum transfer. The elastic scattering of the intermediate energy proton on 4He is studied by applying the KMT multiple scattering theory with microscopic momentum space optical potential. The results show that the phase leads to differential cross section and polarization which are in better agreement with experimental data.
