IMPURITY RADIATION FROM NON-MAXWELLIAN SPHERICAL PLASMAS
The influence of non-maxwellian free electron energy distributions on the steady state de-excitation radiation of not completely stripped impurity ions persisting in homogeneous spherical plasmas is investigated. Following an astrophysical method due to R. N. Thomas, the equation of radiative transfer and that giving the rate of change of the impurity atomic populations, taking into account all radiative and collisional processes involved, are simultaneously solved for arbitrary free electron distributions. As a result, the simple energy loss formula for a two-level impurity atom, calculated without the assumption of Boltzmann atomic distributions, but using maxwellian distributions for free electrons, is rewritten to be valid for arbitrary free electron energy distributions. The possibility of using the corrected formula for spectroscopic purposes is discussed. Numerical examples that emphasize the importance of the correction introduced are presented. (auth)
