High-resolution measurement and quantum-defect analysis of the 8s' and 6d' autoionisation resonances of krypton

Abstract
Photoabsorption cross sections for the 8s' and 6d' autoionisation resonances of the krypton atom have been measured photoelectrically with a photon bandwidth of 7*10-3 AA using the high-resolution spectrometer. The cross sections are parametrised with the aid of a lineshape formula which is based on multichannel quantum-defect theory and has a form analogous with the Fano resonance formula.
