Solar neutrinos from CNO electron capture
Abstract
The neutrino flux from the sun is predicted to have a CNO-cycle contribution as well as the known pp -chain component. Previously, only the fluxes from β+ decays of 13 N , 15 O , and 17 F have been calculated in detail. Another neutrino component that has not been widely considered is electron capture on these nuclei. We calculate the number of interactions in several solar neutrino detectors due to neutrinos from electron capture on 13 N , 15 O , and 17 F , within the context of the standard solar model. We also discuss possible nonstandard models where the CNO flux is increased.
