K-shell photoionization of Li-like Ti XX

Regular Article

Abstract

K-shell photoionization of Li-like Ti XX ions from ground state and first excited state has been studied using the R-matrix method. Through the combination of R-matrix and QB methods, we have not only studied the K-shell photoionization cross section between the first and ninth ionization threshold of Ti XX, but also identified the energy levels of K-shell excited state due to the twelve autoionization Rydberg series.
