Differential and total cross sections and astrophysical S-factors for 2H(d,n)3He and 2H(d,p)3H reactions in a wide energy range

Differential cross sections of deuteron-deuteron fusion reactions are needed in astrophysics, precision cosmology, nuclear physics, and controlled nuclear fusion research. New parametrizations for center of mass differential cross sections, total cross sections and astrophysical S-factors in a wide range of specific energy from 0.5 keV/u to about 0.5 GeV/u have been obtained. Straightforward approximating formulae readily suitable for multithreaded algorithmization are given here for  2H(d,n)3He and 2H(d,p)3H reactions. The energy range is about two orders of magnitude broader than that in the tables published earlier for neutron branch.
