It is known that during the heating of a warm-background ion species by a more energetic ion species, the warm-ion distribution function departs from that of a Maxwellian. It is also known that the velocity dependence of the particle and energy loss mechanisms is a crucial factor in determining the manner in which the bulk ions deviate from Maxwellians. The question of the extent to which these distortions cause an enhanced fusion reactivity in a TFTR-like plasma is addressed. For the cases presented here, no enhancement is found.
