S. Lauer et al., HIGH-RESOLUTION STUDY OF THE PROMINENT NEAR-THRESHOLD RESONANCES IN THE AR 3S-ELECTRON PHOTOIONIZATION, Physics letters. A, 247(1-2), 1998, pp. 167-170
The absolute Ar 3s-electron photoionization cross section was measured
in the exciting-photon energy range from 30.65 to 31.75 eV by photon-
induced fluorescence spectroscopy (PIFS). The bandwidth of the excitin
g synchrotron radiation was 4.8 meV. The profiles of the resonances ob
served in the Ar 3s-electron photoionization were compared with the pr
ofiles of the resonances in the total photoabsorption, (C) 1998 Elsevi
