Bremsstrahlung: Arbitrary Degeneracy and the NonDegenerate Limit

The volumetric production rate of neutronneutron bramsstrahlung as a function of neutron degeneracy. The blue solid line shows the nondegenerate limit. The red dashed line shows the same calculation with the arbitrary degeneracy formalism. The large black square shows the degenerate limit as obtained by Flowers, Sutherland, and Bond (1975). Note that in the first second after core collapse nucleon degeneracies are not expected to be greater than 23.
