Measurements on the angular distributions are reported for D(d,n)³He and D(d,p)³H reactions with E_d ranging from 3 to 6 MeV. The angular range imposed on detection of ³He and ³H in the two reactions respectively was 10° - 40° degrees in the laboratory frame of refence. The evaluated branching ratio σ(d+D→³He+n)/σ(d+D→³H+p), differing in magnitude from the expected value of 1, seemingly suggest the nuclear charge symmetry breaking.
