The helium-3 rich solar flares and the bursts of electromagnetic radiations

Extrahigh ratio of 3He and 4He nuclei fluxes should be considered as the striking quality of the considered flares. Based on the mechanism of helium isotopes strong separation in the solar atmosphere due to plasma effects the concrete model of helium-3 rich solar flare has been suggested by us. If enough number of electrons accelerated at the first phase with an energy of >= 10 keV penetrates the cold plasma of the upper chromosphere, the nonisothermality is formed and due to the nonstability of inverse current an ion-acoustic turbulence on the invasion front is generated. Due to nonlinear interaction of plasmons with the ions the preferential heating of 3He and its injection into the main acceleration process takes place. In this paper we will consider successively the observational consequences of our model
