Abstract:
The properties of the autoionizing 3p511s’ 1/2]1 Argon I level have been experimentally studied in the presence of a strong magnetic field (2.14-2.22 T). Quasi- Landau type oscillations have been observed in the width and position of the 3p5-4p1/2]0 -3p511s’ 1/2]1 exciting transition. The results provide an additional support for earlier observations of Lemoigne et al. 7]. No evidence for similar oscillations in magnetic field dependence of the Fano q parameter was observed.
