Hyperfine structure and isotope shift of high-lying metastable states of rhenium

摘要: Fourteen transitions in ReI, starting from high-lying metastable states belonging to the configurations (5d+6s)7, have been studied by laser-induced fluorescence a collimated atomic beam, and accurate values for isotope shifts these as well hyperfine structure constants of 13 9 excited obtained. In addition, high precision measurements 5d5 6s24D7/2 5d6 6s6D1/2, 3/2, 5/2, 9/2 performed using beam magnetic resonance technique coupled with state-selective detection atoms. The analysis data yields experimental evidence far configuration mixing effects on off-diagonal spin-dipole matrix elements. phenomenological interpretation shows significance field-shift effects.
