Evaluation of the Absolute Angle-Dependent Differential Neutron Production Cross Sections by the Reactions 3H(p,n)3He, 1H(t,n)3He, 2H(d,n)3He, 3H(d,n)4He, and 2H(t,n)4He and of the Cross Sections of Their Time-Reversed Counterparts up to 30 MeV and Beyond

The present status is given of the evaluation of the cross sections of neutron producing reactions among the hydrogen isotopes, and of cross sections of nonelastic two-body neutron scattering from the helium isotopes as obtained by detailed-balance calculations. Absolute angle dependent differential cross sections of all reactions are given at least up to 30 MeV projectile energy, but higher energy data are considered as well. All newly evaluated data are also available in the EXFOR library
