Gamma rays and, for the first time, conversion muons of [ital pt] fusion have been measured from liquid mixtures of protium, deuterium, and tritium. The rate [lambda][sub 10] for spin flip from the triplet to the singlet state of [ital t][mu](1[ital s]) was found to be [lambda][sub 10]=(1.06[plus minus]0.13)[times]10[sup 3][mu][ital s][sup [minus]1], the rate for muon-catalyzed [ital pt] fusion from the ([ital I]=1) nuclear-spin state to be [lambda][sub [ital p][ital t]][sup [ital f]]([ital I]=1) =0.067[plus minus]0.002[sub [minus]0.002][sup +0.005][mu][ital s][sup [minus]1], and the and the molecular formation rate to be [lambda][sub [ital p][ital t]][sup [ital m]]=(7.5[plus minus]0.3[sub [minus]0.3][sup +1.0])[mu][ital s][sup [minus]1] (all rates normalized to liquid hydrogen density).
