Autoionizing 2s22p43s3l States of Ne and Related Ne− Resonances

Abstract

Many autoionizing levels of Ne are seen in the ionization efficiency (I.E.) curve between 42 and 51 eV and reported for the first time. A method to estimate energies of 2s²2p⁴3s3l states leading to the interpretation of our data is presented. Four negative‐ion states are also identified, and their shape factors q and widths $\Gamma$ are given. New techniques had to be developed and are described.
