Description

Photoionization cross sections for ionization to Be+(2s, 2p, 3s, 3p, and 3d) states from the excited 2s3s 1,3S states of atomic beryllium, which contain several autoionizing Rydberg series of resonances converging to the Be+(2p, 3s, 3p, and 3d) states, have been calculated by an enhanced noniterative eigenchannel R-matrix method. Lower members of the Rydberg series of resonances with n≤10 are identified along with the calculated resonance positions Er, effective quantum numbers n*, and widths Γ. The present results are compared with those of previous calculation and very good agreement between them is noted. There is excellent agreement between length and velocity gauges in the present calculation.
