Divalence atomic systems such as the Be isoelectronic sequence are an interesting area for the systematic studies of the photoionization process because of their relatively simple quasi-two-electron structure. Many works have shown that relativistic effects play an important role in the photoionization of small atoms, such as Be [1]. Therefore, it is worthwhile to investigate the interplay between electron-correlation and relativistic effects on the photoionization of atoms or ions with a low nuclear charge. Considerable theoretical and experimental efforts have been made recently to investigate the photoionization of the B + ion. On the experimental side, Janniti, et al. [2] investigated the absorption spectrum of B + for photon energies between 400 and 1700 Å by using two-laser produced plasma; whereas Schippers, et al. [3] studied the photoionization of the B + valence shell using a photon-ion merged-beams arrangement at the Advanced Light Source (ALS). On the other hand of
