Abstract

The γ-ray emission rate by ⁶Li(d,p)⁷ Li^*, ⁷Li^* → ⁷Li+γ reaction when 50∼250 keV proton beam is injected into ⁶Li containing deuterium plasmas (n_e ∼10¹⁹ m^-3 and T_e = 1∼10 keV) is evaluated by simultaneously solving the Boltzmann-Fokker-Planck (BFP) equations for deuteron and proton. A possible experiment to verify the BFP simulations, e.g. knock-on tail effect on T(d,n)⁴ He reaction rate coefficient and/or plasma diagnostics which utilize the tail formation in ion distribution function, is proposed.

Keywords
