In coincidence with tritons from the reaction /sup 208/Pb(/sup 3/He,t)/sup 208/Bi proton spectra corresponding to decay into definite final states in /sup 207/Pb have been measured. The coincidence yield is described as exclusively coming from the decay of two resonances, the isobaric analog resonance (IAR) and the Gamow-Teller (GT) resonance. An analysis in terms of a formation cross section times a branching ratio gives a good description for the IAR and for the shape of the GT resonance. The yield from the GT resonance is however an order of magnitude larger than calculated.
