Aluminium atoms undergoing soft X-ray irradiation produce
multiply-ionized ions in excited states through inner-shell
photoionization followed by radiationless transitions, i.e. Auger
cascades. Photoionization of 2s-, 2p- and 3s subshells are considered
for the 80 eV to 1 keV incident photon energy range. Photoionization
cross sections, shake probabilities and Auger and Coster-Kronig rates
are evaluated in various approximations. Al II, Al III and Al IV UV
lines are directly produced independently of local temperature and
electron density. Monopole shake up/off and conjugate shake up
excitations are important over a large energy interval beyond the L
thresholds.
