S. Ninomiya et al., L-X-RAY-EMISSION FROM SLOW MULTIPLY-CHARGED AR IONS BOMBARDING BE ANDAL TARGETS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 115(1-4), 1996, pp. 177-180
Projectile L X-rays are observed for 18-260 keV Ar-q+ ions(q = 7-14) b
ombarding Be and Al targets. X-ray yields are found to increase with t
he L-shell hole number for q greater than or equal to 9. The X-rays ar
e shown to be emitted stepwise, which allows to disintegrate the spect
ra into the individual steps. It is found that 3s-2p transition is dom
inant in each step. Transitions from higher angular momentum states li
ke 3d-2p and those from higher principal quantum numbers are relativel
y weak.
