Effects of cosmic ray acceleration in relic grains of nanodiamonds in chondrites

Abstract

A new mechanism of the formation of isotopic relations of anomalous Xe-HL component in nanodiamond grains of chondrites under conditions of the propagation of explosive shock waves from supernova outbursts is described, and the regularities of this mechanism are determined. Experimental evidence for the formation by supersonic turbulence of the power-law spectrum of particles with the index γ ∼ 1 in the carbondetonation supernova SnIa explosion is obtained, possibly opening up new prospects for investigating the processes of particle acceleration by shock waves.
