RADIATIVE AND AUGER DECAY PROBABILITIES, BRANCHING RATIOS AND FLUORESCENCE YIELDS OF THE BE-LIKE (1S(2)3 4/') DOUBLY-EXCITED STATES IN NE6+/

Radiative and Auger transitions energies, decay rates, Auger branching ratios and fluorescence yields have been calculated for the Be-like ( 1s(2)3l4l') doubly excited states in Ne6+. The calculations have been performed in the intermediate coupling scheme. The main motivation of this extensive set of theoretical calculations has been to support the analysis and identification of our high resolution soft X-ray photon and Auger electron measurements following single and double electron c apture in Ne8+ + He and Ne8+ + H-2 collisions. The theoretical data co nfirm that the Be-like (1s(2)3l4l') doubly excited states are strongly populated in the Ne6+ + He by double electron capture process.
