Search for resonant electron transfer and double excitation in Kr(sup 34+) + H(sub 2) collisions.

摘要

Resonant electron transfer and double excitation (RME) is a correlated electron process which is expected to occur in an ion-atom collision when electron capture is accompanied by the simultaneous excitation of two inner-shell electrons. RT2 is similar to resonant transfer excitation (RTE) in which only a single electron is excited. RT2E was investigated experimentally for 38--42 MeV/u Kr(sup 34) + H(sub 2) collisions by observing x-ray emission associated with single-electron capture. No events associated with Kr K x rays near 13 keV were observed; however, events do occur at about twice (> 22 keV) the Kr K x-ray energy. Several possible sources of these latter x rays have been considered.
