The autoionising spectrum of atomic mercury excited by electron impact

Abstract
The autoionising energy levels of the mercury atom have been investigated by observing electron ejected following excitation by incident electrons with kinetic energies in the range 20-500 eV. A number of new assignments have been made to levels of the 5d96s2ns, 5d96s26d, 5d106p2 and 5d96s7s configurations, based on both theoretical calculations and quantum defect series analysis.
