The photon spectrum from the reaction /sup 6/Li( pi -, gamma ) was measured with high resolution in the 50- to 150-MeV region by using an electron- positron pair spectrometer. The total fraction of pions absorbed radiatively is 4.4 plus or minus 0.6% with branching ratios to the /sup 6/He ground state of 0.31 plus or minus 0.04% and to the 1.9-MeV state of 0.15 + 0.03% in disagreement with previous experimental results, but in qualitative agreement with theoretical predictions. Evidence for higher excitations is observed in addition to quasifree capture accompanied by neutron emission. (auth)
