HIGH RESOLUTION VELOCITY MAP IMAGING PHOTOELECTRON SPECTROSCOPY OF THE BERYLLIUM OXIDE ANION, BEO-

Abstract

The photodetachment spectrum of $mathrm{BeO^{-}}$ has been studied for the first time using high resolution velocity map imaging photoelectron spectroscopy. Vibrational contours were imaged and compared with Franck-Condon simulations for the ground and excited states of the neutral. The first measured electron affinity of BeO, and anisotropies of several transitions were also measured. Experimental findings are compared to high level textit{ab initio} calculations
