AbstractThe mean energy per neutron for neutrons leaving a dense, laser compressed plasma was calculated. A discrete ordinates multigroup neutron transport code (ANISN) was used to calculate the energies and fluxes of the neutrons from the D(T, ⁴He)n reaction. A variety of constand density, core-burning compressed plasmas were considered. The mean neutron engergy was found to be a function of the product pR and a function of r/R, where R is the compressed plasma radius. A detailed thermonuckear burn in a microsphere was calculated at various time intervals by ANISN. The pR product for the sphere was 4.4 g /cm². The neutron density weighted mean energy per neutron was found to be 9.8 MeV.
