d+d. -->. /sup 4/He+. gamma. cross section measurement at 376 MeV

Journal Article · · Phys. Rev. C; (United States)
Differential cross sections for d+d..-->../sup 4/He+..gamma.. have been measured at theta/sub ..gamma../(c.m.) = 73/sup 0/ and 91/sup 0/ for T/sub d/ = 376 MeV. Our results are a factor of 60 smaller than the cross section measured at T/sub d/ = 404 MeV by Akimov et al. The ratios of our results to those of Arends et al. for the inverse reaction, ..gamma.. /sup 4/He..-->..dd, are 2.0 +- 0.9 at 73/sup 0/ and 1.7 +- 0.9 at 91/sup 0/. Considering the large uncertainties in both data sets, these ratios are consistent with time-reversal invariance in this isoscalar electromagnetic interaction of hadrons. Our data corroborate the reported deviation from the sin/sup 2/2theta angular distribution expected of this reaction.
