Abstract

K-shell photoionization (PI) of Li, Be⁺ and B²⁺ from ground state 1s²2s²S^e have been studied by using the R-matrix method with pseudostates. The K-shell PI process is featured with the contributions from the core-excited metastable states or dominated by the Auger states ²P^o. The resonant parameters of the Auger states ²P^o and the PI cross-sections have been calculated and compared with the available experimental and theoretical works. Our results agree very well with that of the published works. It is worth noting that compared with previous theoretical calculations, our results of B²⁺ show better agreements with the latest high-resolution advanced light source measurements [A. Müller et al., J. Phys. B 43 (2010) 135602].
