在相对论扭曲波脉冲近似(DWIA)的框架下，我们研究了相对论扭曲波脉冲近似(DWIA)下，在入射动能为202 MeV，重合共面散射角($28.0，-54.6)的情况下，不同扭曲光势、有限射程(FR)和零程(ZR)近似下，3s{1/2}，2d${3/2}和2d${5/2}}态质子完全击穿的极化转移观测对不同扭曲光势的敏感性.以及中等修正的介子-核子耦合常数和介子质量。并将结果与基于薛定谔方程的非相对论DWIA预测进行了比较。
Within the framework of the relativistic distorted wave impulse approximation (DWIA), we investigate the sensitivity of complete sets of polarization transfer observables for exclusive proton knockout from the 3s$_{1/2}$, 2d$_{3/2}$ and 2d$_{5/2}$ states in $^{208}$Pb, at an incident laboratory kinetic energy of 202 MeV, and for coincident coplanar scattering angles ($28.0^{\circ}$, $-54.6^{\circ}$), to different distorting optical potentials, finite-range (FR) versus zero-range (ZR) approximations to the DWIA, as well as medium-modified meson-nucleon coupling constants and meson masses. Results are also compared to the nonrelativistic DWIA predictions based on the Schr\"{o}dinger equation.
