Manuel, O., Department of Chemistry, University of Missouri-Rolla. PROTON CAPTURE ON 1abstractACS994N GENERATES EXCESS 15N IN THE SOLAR WIND. The early Apollo missions to the moon and the recent Galileo probe of Jupiter revealed values of the 15N/14N ratio in the solar wind that increased over geologic time [Rev. Geophys. 31 (1993) 423] and strange isotopic abundances of xenon in Jupiter [J. Radioanal. Nucl. Chem. 238 (1998) 119]. The first observation could not be deciphered until the second confirmed that diffusion inside the Sun enriches lighter elements at the solar surface [Meteorit. Planet. Sci. 33 (1998) A97]. Thus, the 1H + 14N => 15O => 15N + - - r€n outside the solar core causes a temporal increase in the 15N/14N ratio in the solar wind. Solar flares disrupt such fusion reactions, leading to an inverse correlation between the solar neutrino flux and sunspot number [Physics Today 43 (1990) 17], and dredge up nitrogen with lower 15N/14N values.
