An effect of nuclear plus interference (NI) scattering on D(d,n)3He, T(d,n)4He and 3He(d,p)4He reaction rate coefficients in 3He-containing deuterium plasma is evaluated on the basis of the Boltzmann-Fokker-Planck (BFP) analysis model. An energetic 3He beam and/or externally-fueled low-energy 3He enhance the 3He(d,p)4He reaction rate from the value for Maxwellian plasma, and increase energetic proton production rate. The energetic protons create the knock-on tail via NI scattering on the fuel-ion velocity distribution functions. It is shown that a recognizable change in the rate coefficients of fusion reactions due to the knock-on tail formation appears.
