- Abstract
- The isotope Nb-92 decays to Zr-92 with a half-life of 3.47 x 10(7) yr. Although this isotope does not exist in the current solar system, initial abundance ratios for Nb-92/Nb-93 at the time of solar system formation have been measured in primitive meteorites. The astrophysical origin of this material, however, has remained unknown. In this Letter, we present new calculations which demonstrate a novel origin for Nb-92 via neutrino-induced reactions in core-collapse supernovae (nu-process). Our calculated result shows that the observed ratio of Nb-92/Nb-93 similar to 10(-5) can be explained by the nu-process.
