Abstract

The hyperfine structure of the 4d2D3/2,5/2 levels of  69,71Ga is determined. The 4p2P3/24d2D3/2 (294.50-nm) and 4p2P3/24d2D5/2 (294.45-nm) transitions are studied by laser-induced fluorescence in an atomic Ga beam. The hyperfine A constant measured for the 4d2D5/2 level is 77.3±0.9 MHz for  69Ga and 97.9±0.7 MHz for  71Ga (3σ errors). The A constant measured for the 4d2D3/2 level is -36.3±2.2 MHz for  69Ga and -46.2±3.8 MHz for  71Ga. These measurements correct sign errors in the previous determination of these constants. For  69Ga the hyperfine B constants measured for the 4d2D5/2 and the 4d2D3/2 levels are 5.3±4.1 MHz and 4.6±4.2 MHz, respectively. The isotope shift is determined to be 114±8 MHz for the 4p2P3/24d2D3/2 transition and 115±7 MHz for the 4p2P3/24d2D5/2 transition. The lines of  71Ga are shifted to the blue. This is in agreement with previous measurement.
