Abstract
New data on the electron-impact excitation of metastable He(2(3.1)S) s tates in the 57-61 eV energy region are presented. Experimental differ ential cross sections for metastable formation were measured with high energy (approximately 0.08 eV) and angular (approximately 0.1-degrees ) resolution by means of a metastable spectroscopy technique. The reso nance-like structure observed is classified as related both to autoion izing and autodetaching states using the density functional theory met hod.
