The hyperfine structure of the 4d{sup 2}D{sub 3/2,5/2} levels of {sup 69,71}Ga is determined. The 4p{sup 2}P{sub 3/2}{r_arrow}4d{sup 2}D{sub 3/2} (294.50-nm) and 4p{sup 2}P{sub 3/2}{r_arrow}4d{sup 2}D{sub 5/2} (294.45-nm) transitions are studied by laser-induced fluorescence in an atomic Ga beam. The hyperfine A constant measured for the 4d{sup 2}D{sub 5/2} level is 77.3{+-}0.9 MHz for {sup 69}Ga and 97.9{+-} 0.7 MHz for {sup 71}Ga (3{sigma} errors). The A constant measured for the 4d{sup 2}D{sub 3/2} level is {minus}36.3{+-}2.2 MHz for {sup 69}Ga and {minus}46.2{+-}3.8 MHz for {sup 71}Ga. These measurements correct sign errors in the previous determination of these constants. For {sup 69}Ga the hyperfine B constants measured for the 4d{sup 2}D{sub 5/2} and the 4d{sup 2}D{sub 3/2} 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 4p{sup 2}P{sub 3/2}{r_arrow}4d{sup 2}D{sub 3/2} transition and 115{+-}7 MHz for the 4p{sup 2}P{sub 3/2}{r_arrow}4d{sup 2}D{sub 5/2} transition. The lines of {sup 71}Ga are shifted to the blue. This is in agreement with previous measurement. {copyright} 2001 Optical Society of America
