Resonances in the differential excitation functions of five electronic states of Ne in the autoionization region

Abstract

We have observed many resonances by electron spectrometry in the differential excitation functions of the states $3s$, $3{s}^{\ensuremath{'}}$, $3{p}^{\ensuremath{'}}$, $4{s}^{\ensuremath{'}}$, and $3d$ of neon in the autoionization region. These measurements are compared to the data obtained by other spectroscopic methods and their interpretation is discussed. For the main resonances, the energies and natural widths are determined. Moreover, their effective strengths and profile indices are presented for the various decay channels in comparison with the data obtained in the ionization channel.
