Photoelectron Spectroscopy of the Beryllium Pentamer Anion

Abstract

Beryllium is known to be a challenging test for even high level ab initio methods due to high electron correlation contributions. There is fundamental interest in understanding how well computational methods can predict physical properties of beryllium containing molecules, but very little available experimental data on these molecules. We have continued in our exploration of pure beryllium clusters, and have acquired preliminary spectra for the beryllium pentamer Be 5 . In this talk we will present our work to date on Be 5 , with comparisons to theory and the Beryllium tetramer
