Abstract

The hyperfine structures of six metastable levels arising from the 3d24s and 3d3 configurations in i49 have been measured with high precision using the laser-rf double-resonance technique in a collinear laser-ion-beam geometry. The hfs constants A and B were determined to about 4 and 43 kHz, respectively. Less precise results are also reported for the 2p1/2 level of the 3d3 configuration and for five upper levels in the 3d24p configuration. For these states, the optical spectra had Doppler widths of about 40 MHz, leading to A values determined to about 1 MHz. The results are compared with the presently available Hartree-Fock (HF) calculations. Good agreement is obtained with the HF results only in some cases. Substantial corrections due to many-body interactions and relativistic effects are required for other cases. © 1992 The American Physical Society.
