I discuss three issues relevant to solar neutrino flux measurements: cross section uncertainties in pp chain reactions, uncertainties in the GALLEX/SAGE response to 7 Be and 51 Cr neutrinos, and the implications of helioseismology for nonstandard suns with mixed cores. A few comments are also offered on νe ↔ ντ oscillations, cosmologically interesting neutrino masses, and recent proposals for s...

We extend our previous studies of the neutrino-induced reactions on 12 C and muon capture to include partial occupation of nuclear subshells in the framework of the continuum random phase approximation. We find, in contrast to the work by Auerbach et al., that a partial occupation of the p 1/2 subshell reduces the inclusive cross sections only slightly. The extended model describes the muon cap...

The question whether there is a pion transparency in 500 MeV C(π, π ′ ) scatterings is studied using a semiclassical, hadronic transport model. The double differential cross sections of this reaction measured at LAMPF can be largely accounted for, if one uses energy-dependent, anisotropic angular distributions which are fitted to pion-nucleon scattering data for the decay of ∆(1232) and N(1440)...
