摘要：

A novel technique for processing line-shape data for the Thomson electron feature is described. It involves 'fitting' the Thomson model to line-shape data by simply measuring essential characteristics of the line shape, referred to as shape parameters, instead of fitting by iteration and adjustment of the implicit variables, the electron temperature, T, and number density, N. One shape parameter is the ratio of the height of each satellite peak to that of the valley, a ratio that is uniquely related to N/T; the other is the wavelength shift of each peak from the central wavelength.
