Generalized Oscillator

A realistic analytical central potential with two adjustable parameters is used to generate wavefunctions for the ground and excited states of doubly ionized boron. Generalized oscillator strengths and integrated cross sections from threshold up to 5 keY are calculated in the Born approximation for 2s-ns, 2s-np and 2s-nd excitations. Convenient analytic formulae for the cross sections are presented.

Impact Experiments

The ejected electron spectra of K and Ca vapours following electron impact excitation of the 3p-subshell have been compared with Hartree–Fock calculations. Most K ɪ and Ca ɪɪ 3p 5 3d 4s levels have been identified, albeit tentatively in many cases. A detailed analysis of low energy K ɪ lines is presented, including some minor changes to earlier assignments of photo-absorption lines. A good general description of the low energy ejected electron spectrum of Ca has also been achieved, almost exclusively in terms of autoionization of Ca ɪɪ levels.
