英文摘要	We have measured the L-shell X-rays of iodine from the collisions of 3 MeV I-q+(q=15,I-20,I-22,I-25,I-26) ions with an iron target. It is found that the X-ray yield decreases with the increasing initial charge state. The energy of the subshell X-ray has a blue shift, which is independent of the projectile charge state. In addition, the relative intensity ratios of L beta(1,3,4) and L beta(2,15) to L alpha(1,2) X-ray are obtained and compared with the theoretical calculations. That they are larger than for a singly ionized atom can be understood by the multiple ionization effect of the outer-shell electrons. (C) 2014 Elsevier B.V. All rights reserved.
