Interaction of highly charged Xe^q+ (q = 26, 27, 30) ions with molybdenum surface

Experimental investigation of Molybdenum L-shell X-ray emission is reported in the collision of highly charged Xe^q+ (q = 26, 27, 30) ions with Molybdenum surface in the energy range 400 to 600 keV. Based on the X-ray spectra obtained and by the extrapolation of experimental data to the lower incident energy range, a limit was found for the energy of the incident ions. The influence of initial charge state on X-ray emission from the target L-shell was observed. The difference of the initial charge state and electron configuration of the incident ions may lead to observably different contribution to the target atom vacancy production and L-shell X-rays emission. Based on COB model, a simple explanation was presented to interpret the features of the experimental results.
