Abstract: | By optical means (i.e. hollow cathode, Fabry-Perot-interferometer and spectrograph) the hyperfine structure of 15 transitions in the Re-I spectrum was investigated. This permits to state the hfs coupling constantsA, B for 15 levels belonging to the configurations (5d 5) 6s 2, (5d 5) 6s 6p, (5d 5) 6s 7s, (5d 6) 6s, (5d 6) 6p and (5d 4) 6s 2 6p. It was found that the (5d 5) 6s 2 6 S 5/2 ground state, too, shows a small hfs. Of its magnetic splitting both size and sign could be determined (A 0,185,187=?2,2±0,4 mK); for a possible quadrupole splitting upper limits were obtained. Estimates of the quadrupole moments resulted inQ 185,187?2,9b. — In the case of two levels (x 6 P 7/2 andy 6 F 11/2) the hfs analysis raises doubts as to their classification. |
