The formation of Ne-E, the anomalous component of neon, in nuclear reactions with fast particles accelerated during a local supernova explosion 4,700 Myr ago, is considered. The irradiation parameters are determined on the basis of the observed abundance of Li, Be, and B isotopes. The dependence of Ne-E(L) and Ne-E(H) contents in graphitic grains and silicon carbide on the cut-off and the form of the spectrum of accelerated particles is analyzed. Comparison of the results of the calculation with the available measurements in chondrites unambiguously testifies in favor of the origin of Na-22, the radioactive progenitor of Ne-E, in nuclear reactions at the shock front in the expanding supernova shell.
