Experimental and theoretical study of 3p photoionization and subsequent Auger decay in atomic chromium

3p photoionization and subsequent low kinetic energy Coster–Kronig and super Coster–Kronig Auger decay have been studied in atomic chromium. The binding energies, line widths, and relative intensities for the transitions seen in the synchrotron radiation excited 3p photoelectron spectrum are determi...

Summary:3p photoionization and subsequent low kinetic energy Coster–Kronig and super Coster–Kronig Auger decay have been studied in atomic chromium. The binding energies, line widths, and relative intensities for the transitions seen in the synchrotron radiation excited 3p photoelectron spectrum are determined. The high resolution M2,3M4,5M4,5 and M2,3M4,5N1 Auger electron spectra following the electron impact excited 3p ionization are presented and the kinetic energies, relative intensities, and identifications are given for the main lines. The experimental findings are compared with the theoretical predictions obtained from Hartree–Fock and multiconfiguration Dirac–Fock approaches. •Synchrotron radiation excited Cr 3p photoelectron spectrum.•High resolution Auger decay following Cr 3p ionization.•Widths of the photoionized states.•Identification and energies of the Auger decay.
