Photoionization of Ge¹³ in the Inner-Shell 2p Excitation Energy Region

The photoionization cross sections of the levels belonging to the ground configuration [Ne]3s²³p⁶³d of Ge¹³ are investigated using the fully relativistic R-matrix method in the 2p-3d excitation region. The photoionization cross section is dominated by 2p-3d resonances. The detailed resonance structures are described and analysed with the resonance positions, widths and oscillator strengths to be determined. Good agreement is obtained between the length and velocity forms of the resonance oscillator strengths. The relative difference is less than 8%.
