Excitation of the 3p$^{5}$5p levels of Argon from the 3p$^{5}$4s metastable levels

In the light of recent experimental results of Jung et al [1] we have extended our relativistic distorted wave (RDW) calculations [2] to the electron impact excitation of the ten higher-lying fine-structure levels of the 3$p^{5}$5$p$ configuration of argon from the lowest metastable states (the J = 0, 2 levels of the 3$p^{5}$4$s$ configuration). We compare our theoretical results with their experimental results and discuss the differences from the similar excitation to the 3p$^{5}$4p levels from the same metastable states [2]. [1] R. O.
