Abstract : Relative cross sections have been measured for the D(d,p)3H and D(d,n)3He reactions from 300 keV to 700 keV in 50 keV steps. The ralative values have been normalized to existing cross sections in order to obtain absolute values. Angular distributions of all charged particles from the reactions were taken from 20 degrees to 160 degrees in 10 degree intervals in the laboratory system. Energy dependent asymmetry coefficients from the expansions of the center-of-mass angular distributions in terms of even powers of Cos theta are obtained as are the branching ratios between the two reaction modes. The different energy dependences of the moments of the two cross sections are discussed in relation to existing theories. (Author)
