Abstract
Near-threshold electron impact spectra in Ne, demonstrably free of post-collision interaction (PCI) effects and negative-ion resonance structures, have been obtained as a function of scattered energy over the energy range from 41 to 52 eV. The author finds that single-electron transitions 2s22p6 to 2s2p6nl dominate over two-electron transitions 2s22p6 to 2s22p4nln'l' and that states with terms 1S and 3P are preferentially excited. Detailed comparisons with previous theoretical and experimental data are made, in particular with those obtained by threshold electron impact techniques where PCI and negative-ion resonances are often a complicating issue.This publication has 32 references indexed in Scilit:
