Tenemos una amplia gama de equipos disponibles en todo el Ecuador. 38. Solar neutrinos are produced in the core of the Sun through various nuclear fusion reactions, each of which occurs at a particular rate and leads to its own spectrum of neutrino energies. Details of the more prominent of these reactions are described below. The main contribution comes from the protonâproton chain. neutrino properties from cosmology ... Bahcall has recently published an article arguing that there may be no solar neutrino problem at all.
