Effect of deviations from the Maxwell distribution on neutron production in laser targets

The ion distribution and the deuterium tritium fusion reactivity (sigma v) were calculated. Results are presented for the ratio of (sigma v) for a monoenergetic isotropic distribution to that for a Maxwell distribution, for the rate of approach of (sigma v) to the equilibrium value, and for the decay of (sigma v) due to fast ion losses. The main effect in the last case is due to energy losses, not to non-Maxwellian distribution. The effect is substantially different than previously reported.
