Recalibration of the Auger spectra of boron

By using saddle-point technique, 12 autoionizing and two metastable autoionizing states of B III are calculated. To obtain high accuracy relativistic effects and mass polarization effect are included in the computation. Spin-orbit, spin—other-orbit, and spin-spin effects are also considered. Using the B IV $\left(1\mathrm{}{s}^2\right){}_{}{}^1{}_{}{}^{}S$ result of Pekeris the corresponding Auger energies are tabulated. These data are then used to recalibrate the reported boron electron spectra of Rødbro, Bruch, and Bisgaard by about 0.15 eV. The calculated energies enable us to make seven new identifications in the boron Auger spectra. The fine-structure calculation also reveals many inverted $J$ levels among these core-excited states.
