Photodetachment studies with the linear time of flight photoelectron spectrometer

Abstract

A linear time of flight photoelectron spectrometer was built for photodetachment studies on anions. The design of the newly constructed photoelectron spectrometer is discussed briefly. Angular distribution of photoelectrons in the photodetachment from OH⁻, As⁻ and Cu⁻ were measured at a few distinct wavelengths. Energy dependence of the asymmetry parameter was studied for these anions. The relation between electronic configuration and the energy dependence of the asymmetry parameter is briefly discussed.
