摘要：

The review discusses the solar system (meteoritic) abundances and the possible modes of nucleosynthesis of the 30-odd p-nuclei from Se-74 to Hg-196. In addition to a discussion of the abundances for bulk meteorites, isotopic anomalies related to the p-nuclei are discussed; e.g., the Xe-HL associated with the 'interstellar' diamonds and the extinct radionuclides Sm-146 and Nb-92. Various proposed schemes of synthesizing p-nuclei are reviewed. It is noted that the gamma-process (i.e., photoerosion) operating in SN la (exploding C-O white dwarfs) appears capable of accounting for the relative and absolute abundances of all but one or two of the rarest of p-nuclei. Synthesis of these latter nuclei is also discussed.
