Model potential calculations and spectroscopic observations of some doubly excited states in beryllium-like Ne VII

Abstract
Energy level positions and branching ratios for radiative decay have been calculated for a number of doubly excited states in beryllium-like Ne VII using the SUPERSTRUCTURE code. These are compared with weak unidentified features observed in spectra obtained from foil-excited neon beams at energies of 6, 13 and 18 MeV.
