Abstract
The interaction of light and matter is a fundamental interaction in nature. In general, a detailed understanding of correlated dynamics involved in photoionization and photofragmentation is an opportunity for the advancement of both experimental and theoretical physics. The UNR COLd Target Recoil Ion Momentum Spectroscopy (COLTRIMS) apparatus has been developed to act as an experimental technique to investigate many-particle dynamics associated with photoionization at a range of user facilities. The possibility to determine soft X-ray site-specific ionization for identical mass atoms within a molecule is an open question in quantum physics. This dissertation details a study of two isomers, 1,1 and 1,2-trans dichloroethene, designed to investigate the phenomena of site-specific localized core-hole ionization. This experiment used photoionization of chlorine atoms within dichloroethene performed at the Advanced Light Source beam-line 9.0.1 at Lawrence Berkeley National Lab in November 2019. In the 1,1 dichloroethene data set, state and bond-length dependent core-hole localization was shown following chlorine L-edge ionization.
