Strong molecular field effects in Auger decay of the potassium 2p core-hole state in molecular KCl, KBr and KI

In English The K 2p photoionization and subsequent LMM Auger decay have been studied for molecular gas-phase KCl, KBr and KI. The detected manifold spectral structure of the Auger electron spectrum of KCl has been interpreted to originate from strong molecular field effects. This indicates that Auger decay on potassium side of originally very ionic molecules creates inner-shell hole states with a strong molecular character.
