Abstract

Absolute photoionization cross-section measurements are reported for Se⁺ in the photon energy range 18.0-31.0 eV, which spans the ionization thresholds of the ⁴S_3/2 ground state and the low-lying ²P_3/2,1/2 and ²D_5/2,3/2 metastable states. The measurements were performed using the Advanced Light Source synchrotron radiation facility. Strong photoexcitation-autoionization resonances due to 4p → nd transitions are seen in the cross-section spectrum and identified with a quantum-defect analysis.
