There is a widespread assertion in the literature that the optical Ga
lines give much higher abundances than the UV lines. We have determined
Ga abundances in HgMn stars taking the observed hyperfine structure of the
optical Ga II lines into account. This reduces these abundances to
within 0.2 dex of the values from the resonance lines.
