Description
Analyzing the solar system abundance, we find two universal scaling laws concerning the p and s nuclei. They indicate that the γ process in supernova (SN) explosions is the most probable origin of the p nuclei that has been discussed with many possible nuclear reactions and sites in about 50 years. In addition, the scalings lead to new concepts: a universality of the γ process and a new nuclear cosmochronometer. We carry out γ-process nucleosynthesis calculations for typical core-collapse SN explosion models, and the results satisfy the observed scalings
