摘要：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 7 Li and 11 B, namely 7 Be and 11 C, are not decomposed in the mixture, so that the 11 B/ 7 Li ratio is determined by the 11 C/ 7 Be ratio after 7 Li and 11 B are completely decomposed. On the other hand, the CNO-elements are almost free from the nuclear reprocessing after the mixing. The small ratios of 6 Li/ 7 Li and 9 Be/ 7 Li, and the diagram of 11 B/ 7 Li- 12 C/ 13 C obtained in the previous studies are still valid.
