Differential cross sections have been measured for p+d..--> gamma..+/sup 3/He at T/sub p/(lab) = 300, 350, 400, 425, 450, 470, and 500 MeV for theta/sub ..gamma../(c.m.) near 60/sup 0/ and 90/sup 0/. Measurements were also made for d+p..--> gamma..+/sup 3/He at T/sub d/ = 376 MeV for theta/sub ..gamma../(c.m.) = 84/sup 0/, 98/sup 0/, and 113/sup 0/, and at T/sub d/ = 600 MeV for theta/sub ..gamma../ = 96/sup 0/ and 105/sup 0/. Our results are in agreement with those of the inverse reaction, ..gamma..+/sup 3/He..-->..p+d of Sober et al., as is expected from time-reversal invariance. Our data agree with the latest results of Cameron et al. The older radiative capture measurements of Heusch et al. and the photodisintegration measurements made at other laboratories differ significantly from our results. Our data are compared with three theoretical models; the one proposed by Maximon and Prats comes closest to describing the data.
