The results of January 20, 2005 solar flare study by narrow gamma lines

Abstract

Abstract.We have studied some properties of the powerful solar flare of January 20, 2005 by methods of nuclear lines analysis. The results of temporal profiles investigation in corresponding to neutron capture energy bands allow the supposition about predominant acceleration of 3 He ions in the corona, their subsequent propagation to the low chromosphere and the photosphere where the area of 2.223 MeV γ-line effective productions is located. The characteristics of accelerated 3 He ions propagation processes and the basic explanation of observable properties of this solar flare due to the variations of 3 He content are discussed in the presented article.
