摘要
分析反质子在入射能量低于200MeV 时与原子核的弹性和非弹性散射现象.多次散射的特点很显著.反质子的光学势要求是强吸收型.极化度 P(θ)的实验要求这个光学势应拓广包含自旋轨道耦合项.扭曲波冲量近似理论在描述非弹性过程获得良好的效果.但若要求包含对反常核态的激发,则扭曲波应来自含自旋轨道耦合势下的结果.
An analysis of antiproton-nucleus elasctic and inelastic scattering at incidet energies below 200 MeV.shows that the charactor of multiscattering is dominant. The antiproton optical potential is of the type of strong absorption,and the experimen- tal polarization data ask for the extension of this optical potential to include the spin-or- bit coupling term. The theory of distorted wave impulse approximation can be used to describe the antiproton-nucleus inelastic scattering.However,the distorted wave should be the soiution of optcal potential with spin-orbit term if the abnormal parity states are to be stusied.
