On the Anticorrelation Between the HE3/HE4 Ratio and Proton Intensity in HE3-RICH Flares
Abstract
A model is presented to explain the observed anticorrelation between the size of the He(3)/He(4) abundance ratio at not less than about 10 MeV/nuc and the peak intensity of about 10 MeV protons in the He(3) rich events. The anticorrelation is shown to be a natural consequence of producing abundance enhancement by a two step acceleration process, where He(3) is preaccelerated with respect to He(4) prior to the main ion acceleration phase, which has an effective injection cutoff varying from flare to flare.
