Hyperfine and isotope structure have been studied in 18 Ga II lines, record
ed with Fourier transform spectroscopy. For 12 of the lines the observed pa
tterns could be analysed, yielding magnetic hyperfine structure constants A
for eight Ga II levels. Improved wavelengths are given for a number of pro
minent Ga II lines, including centres of gravity and the individual hyperfi
ne and isotope components of the lines with significant structure.
The components of the spin-forbidden transition 4s(2)4p P-2-4s4p(2) P-4 in
Ga I have also been analysed and absolute wavelengths and hyperfine constan
ts A are reported.
