On the power scattered from density fluctuations in a plasma

The power spectral density for scattering from density fluctuations in a plasma was numerically integrated to check an approximate analytical ex pression for the total scattered power. For all wavelength - Debye-length ratios, the analytical expression decreases monotonically with increas ing electron-ion temperature ratio. The numeri cal results differ significantly from this be havior only for temperature ratios greater than to a maximum for large temperature ratios. The discrepancy is more important for less massive ions and for larger-wavelength - Debye-length ratios. (Author)
