Aj. Willes et Pa. Robinson, IMPROVED PREDICTIONS OF ELECTRIC-FIELD STRENGTHS AND VOLUME EMISSIVITIES IN 2ND-HARMONIC TYPE-III SOLAR RADIO-EMISSION, Solar physics, 170(2), 1997, pp. 341-356
Previous comparisons between predicted and observed electric field str
engths and volume emissivities in second harmonic type III solar radio
emission are improved in two ways. First, the assumption of the head-
on approximation in deriving the harmonic emission rate, which is not
applicable over the full range of observed type III parameters, is rep
laced with a more suitable approximation. Secondly, a more realistic f
unctional form for the Langmuir wave spectra is adopted. The revised p
redicted electric field strengths and volume emissivities are consiste
nt with the observed values.
