Bremsstrahlung Rate and Spectra from a Hot Gas (Z=1)

Abstract

An interpolation between the quadrupole and extreme relativistic electron-electron brems-strahlung contribution to the emission rate and spectra from a Maxwell-Boltzmann electron gas is carried out. These results are then added to the "exact" electron-ion results already in the literature to give the total emission for the temperature region $1 \mathrm{keV}\le k{T}_e\lesssim 0.3 \mathrm{MeV}$. It is found that quadrupole corrections are sufficient until the temperatures reach $k{T}_e\simeq 100$ keV. At higher temperatures all multipoles must be included in order to describe the emission accurately.
