Abstract

The properties of alpha particle fluxes, the density of which increase under the action of flares and development of coronal mass ejections (CMEs) and solar wind structural inhomogeneities, have been studied. The maximal alpha particle density in plasma fine structure volumes reaches 12 cm−3. The amount of α particles is sometimes higher than that of protons. This is explained by the effect of the mechanism by which individual solar wind zones are nonuniformly enriched in helium nuclei when strong flares develop.
