Abstract

The hyperfine structure of the53Cr resonance linesa 7 S 3 ↔z 7 P 2,3,4 has been investigated by means of laser saturation spectroscopy. By comparison of the experimental signal curves with theoretically computed spectra the hitherto unknown sign of the magnetic hyperfine coupling constant in thea 7 S 3 ground state of53Cr could be determined unambigiously to be negative. Further the signs of the hfs coupling constants in thez 7 P states — so far only evaluated by theoretical reasoning — could be confirmed. Additionally the lifetimes of the statesz 7 P,z 5 P,f 7 D,z 5 F,e 7 D 5 andy 5 P 3 in the Cr I spectrum have been determined from the fluorescence decay after pulsed laser excitation.
