Abstract

The particle kinetic energies of thermonuclear pp fusion in the Sun (Gamow energy) produce small changes in the energies of pp solar neutrinos relative to those due only to exothermal energetics. This effect may be observable via the unique tools of the LENS solar neutrino detector. The temperature profile of energy production in the Sun may thus be directly probed for the first time.
