Abstract
We report on a nonperturbative $R$-matrix with PseudoStates (RMPS) calculation for the electron-impact ionization cross section of the ground state of ${\mathrm{Al}}^{2+}$. We include both the direct ionization of the $3s$ and $2p$ subshells and the indirect ionization from the $2p$ subshell. This calculation, thus, includes extra decay channels for the indirect-ionization process not included in previous RMPS calculations. This lowers the total-ionization cross section, resulting in closer agreement with the most recent experimental measurements. This calculation also shows better agreement with the position and height of the resonant-excitation double autoionization features seen in the experiment.
