【 摘 要 】

Dissociation of OCS upon various Auger decay transitions due to ionization at sulphur 2p1/2threshold is studied. A combination of Recoil Ion Momentum Spectroscopy and electron energy analysis are employed to perform these studies. It is observed that the dissociation channels and their branching ratios vary with the binding energy of the Auger decay state. The kinetic energy release distribution (KERD) upon fragmentation of the molecule for various Auger transitions have also been examined.
