Abstract
AbstractThe L-shell X-ray emissions of iodine are investigated as a function of the incident energy for I22+ions impacting on Fe target in the energy region near the Bohr velocity. Six distinct L-subshell X-rays, Lι, Lα1, 2, Lβ1, 3, 4, Lβ2, 15, Lγ1and Lγ2, 3, 4, 4', are observed. Compared to the atomic data, the energy of the experimental X ray shifts to the higher energy side. The relative intensity ratios of Lι, Lβ1, 3, 4, Lβ2, 15, to Lα1, 2, Lι to Lβ2, 15and Lγ2, 3, 4, 4/to Lγ1are enhanced, but has no obvious change with the increase of projectile energy in the present energy region. That is interpreted by the multiple ionization effect of the M-, N- and O-shell electrons.
