The power density of bremsstrahlung and the recombination rate are found for a fully ionized, nonrelativistic hydrogen plasma dominated by long-range collisions. The results show that the bremsstrahlung energy radiated per unit volume per second is greater than previously predicted.

The cross section for an electron to emit two photons while being accelerated by a hydrogen nucleus is derived using Born approximation. The result suggests that such multiple photon emission processes are insignificant compared to the usual bremsstrahlung radiation process in laboratory and thermonuclear hydrogen plasmas.

A comparison of one photon and two photon bremsstrahlung processes in hydrogen plasmas

Debye shielding corrections to one and two photon cross-sections for bremsstrahlung in a plasma are determined. It is found that the corrections are small for typical Tokamak thermonuclear parameters, but may be important in the dense-plasma focus and laser fusion plasmas.
