The results from our theoretical work are compared with recent measurements made at the Advanced Light Source (ALS) radiation facility in Berkeley, California, USA. We report on results for the photon energy range 18.0 eV -- 31.0 eV, which spans the ionization thresholds of the $\\rm ^4S^o_{3/2}$ ground state and the low-lying $\\rm ^2D^o_{5/2,3/2}$ and $\\rm ^2P^o_{3/2,1/2}$ metastable states.
