Abstract
A theoretical study of the photoionization of the 1S ground state of Be-like B+ ion leading to the 2s, 2p, 3s and 3p states of B2+ has been performed using a noniterative eigenchannel R-matrix method. The autoionizing Rydberg series which converge to the various levels of B2+ limits up to 3d are identified and characterized. In addition, a calculation of the photoionization of the 2s2p 3Po metastable state of B+ ion was performed to compare the results with recent work on the photoionization of a mixture of ground and metastable states of the B+ ion. Excellent agreement with recent experiment and associated theory in the photon energy range 22–31.3 eV was found. The present calculation is also in overall reasonable agreement with a previous Opacity Project (OP) calculation, and excellent agreement between length and velocity gauges is found.
