Electron-electron bremsstrahlung in a non-equilibrium plasma

Abstract

Electron-electron bremsstrahlung in a weakly ionized uniform non-stationary plasma is investigated. The respective problem is solved analytically for two initial electron-distributions: maxwellian with the temperatureT ₀, and the delta distribution. In the case of initial maxwellian distribution the radiation intensity is proportional toΘ ^3/2, whereΘ=T+(T ₀−T) exp (−s),s=2mv ₁ t/M,v ₁ is the momentum transfer frequency, and the other symbols are standard. In the case of initial delta distribution the radiation intensity is proportional to [1 -exp (−s)]^3/2. The proportionality factors are known, and are expressed in terms of mathematical and physical constants.
