Abstract
This is the third paper of a series of our papers, in which we have investigated explosive nucleosynthesis of the X-elements (Li, Be, and B) and the CNO-elements in supernova explosions. We concentrate here on evaluating the varieties of the isotopic/elemental ratios of the light elements due to the mixing process between the He-layer and the H-rich envelope of a supernova taking account of nuclear reprocessing after the mixing. Almost all of the X-elements are influenced strongly by the nuclear reprocessing after the mixing; the X-elements produced in the He-layer are decomposed by protons in the H-rich envelope even if the He-component mixes with a bit of the H-component. The p-rich isobars of 7Li and 11B, namely 7Be and 11C, are not decomposed in the mixture, so that the 11B/7Li ratio is determined by the 11C/7Be ratio after 7Li and 11B are completely decomposed. On the other hand, the CNO-elements are almost free from the nuclear reprocessing after the mixing. The small ratios of 6Li/7Li and 9Be/7Li, and the diagram of 11B/7Li-12C/13C obtained in the previous studies are still valid.
