摘　　要：对于能量为０．５－１ＭｅＶ的入射质子，在计算中采用ＡｕＬ１次壳层荧光产额的实验值代替相应的Ｄｉｒａｃ－Ｈａｒｔｒｅｅ－Ｓｌａｔｅｒ值时，使用ＲＰＷＢＡ－ＢＣ（经结合能和库仑歪曲修正的相对论平面波玻恩近似）电离截面计算得到的金原子ＬＸ射线相对产生截面与测量值相符。For incident protons with energies from 0.5 to 1 MeV,a good agreement between theoretical Au LX ray relative production cross sections calculated by using the RPWBA BC(relativistic plane wave Born approximation with the binding and Coulomb deflection corrections) ionization cross sections and experimental data was obtained when the experimental L 1 subshell fluorescence yield was adopted instead of the corresponding Dirac Hartree Slater value in the calculations.The reported modifications to the RPWBA BC cross sections are undesirable.
