Dependence of radiative stabilization on the projectile charge state after double-electron-transfer processes in slow, highly charged ion-molecule collisions
- National Institute for Fusion Science, Nagoya 464-01 (Japan)
We have measured the radiative stabilization probabilities after double-electron-transfer processes in slow (1.5qkeV) I{sup q+}+CO collisions in the charge-state regime 8{le}q{le}26 by using the charge-selected-projectile{endash}recoil-ion-coincidence method. It was found that the radiative stabilization probabilities P{sub rad}, defined as P{sub rad}=T{sub DC}/(T{sub DC}+A{sub DC}) (T{sub DC} is true double capture, and A{sub DC} autoionizing double capture), increases from about 1{percent} at the lowest charge up to about 10{percent} at the highest charge as the charge state of the projectile increases. A model is proposed which can explain such a feature, by incorporating a slight modification of the initial population of the transferred levels in the projectile predicted in the extended classical over-barrier model. Based upon the present model, theoretical radiative and autoionization decay rates have been calculated, using the Cowan code. Fairly good agreement between the measured and calculated results has been obtained. {copyright} {ital 1997} {ital The American Physical Society}
