Photoionization of the Li atom: Convergent-close-coupling calculations with a focus on two-electron removal

Year: 2026

Type: article

Abstract: In a combined experimental and theoretical study, Müller [] revealed highly detailed resonant structure in ionization with excitation and in double ionization of the Li-like B 2 + ion. That work demonstrated the strong predictive power of the convergent-close-coupling (CCC) method when enhanced by modern supercomputing technology. In the present work, we apply CCC to analogous ionization processes in the Li atom. Again, we find K -shell ionization accompanied by K -shell excitation to contribute relatively strongly to the double photoionization of three-electron Li. Comprehensive detailed comparisons with the existing experimental data are presented and discussed.
