Description
Summary:The radiative and Auger emissions in cascade (RAC) model constructed earlier (G. Omar and Y. Hahn, Phys. Rev. A (to be published)) is applied to the calculation of the final-charge-state distribution in the decay of Ar{sup +}(1{ital {bar s}}) with an initial 1{ital s} hole created by synchrotron irradiation. Experimental data of Church {ital et} {ital al}. (Phys. Rev. A 36, 2487 (1987)) are reasonably well reproduced, including the observed asymmetry in the final-state charge distribution. In addition to Ar{sup +}(1{ital {bar s}}), we have also considered the decay of the initial states Ar{sup +}(2{ital {bar s}}), Ar{sup +}(2{ital {bar p}}), and Ar(1{ital {bar s}},4{ital p}). The higher charge states are underestimated by the RAC model, presumably due to the neglect of correlated multielectron processes in the present calculation.
