On the balance of the solar p-p chain

Abstract

I show that the solar neutrino fluxes, predicted by standard nuclear and solar physics, can get closer to the experimental observations if one takes the freedom to introduce two free parameters into the model, as it is done in the MSW solution. I point out that the plasma electron capture of Be7 and the He3(He3,2p)He4 nuclear reactions deserve further experimental and theoretical attention.
