Charge state and pressure dependence of characteristic X-ray emission in collisions of Xe ions with rare-gas atoms

The charge state dependence of K and L X-ray emission has been studied for 1.4 MeV/N Xeq+ (24 26. Dynamic couplings between molecular orbitals in the transiently formed quasimolecule are found to be responsible for this increase. Parameters characterising these couplings are estimated. The observed pressure dependence of K and L X-ray emission is found to be due to charge state changing effects.
