A REVIEW OF ELECTRON-IMPACT COLLISIONAL EXCITATION DATA FOR THE OXYGEN-LIKE ISOELECTRONIC SEQUENCE

Published data on electron impact cross sections for ions of the oxygen-like isoelectronic sequence from 1953 to the present are reviewed. All transitions for which tabulated data are available are listed and classified according to source, type, method, and year of publication. Where possible, Maxwellian averaged collision strengths are computed at a standard set of atomic charge scaled electron temperatures. Compatible effective collision strengths are assembled into data sets that allow interpolation in charge and electron temperature and are suitable for excited level population studies.
