摘要：

If the low energy cross section for He-3 + p --> He-4 + e(+) + nu(e), the 'hep' reaction, is greater than or similar to 20 times larger than the best (but uncertain) theoretical estimates, then this reaction could significantly influence the electron energy spectrum produced by solar neutrino interactions and measured in the SuperKamiokande, SNO, and ICARUS experiments. We compare predicted energy spectra for different assumed hep fluxes and different neutrino oscillation scenarios with the observed SuperKamiokande spectrum. The spectra with enhanced hep contributions provide better fits to the SuperKamiokande data. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
