Abstract: 
We have investigated L-shell photoionization (PI) of IS ground-state and 3 p, metastable states of the Be-like ion, B+, in the photon energy range 22.4-31.3 eV, at an experimental energy resolution of 25 meV Absolute PI cross sections have been measured using a photon-ion merged-beams arrangement at the Advanced Light Source. Detailed calculations using the semi-relativistic Breit-Pauli R-matrix approach suggest a fraction of 29% of metastable ions in the primary beam of the experiment. Excellent agreement is observed between the theoretical predictions and the experimental high-resolution PI cross sections. The present results are compared with earlier experimental and theoretical work. The cross section for PI of B+ ground-state ions can be very well described by an analytic formula derived from quantum defect theory.
