Abstract
The astrophysics and the particle physics of solar neutrinos can be tested independently by two line signals induced by neutral (NC) and charged current (CC) neutrino reactions on $^{7}\mathrm{Li}$, in a high-resolution, bolometric, 4-ton LiF detector. The NC \ensuremath{\gamma}-ray line signal measures the flux of neutrinos of all flavors with ${\mathit{E}}_{\ensuremath{\nu}}$>0.478 MeV, setting a firm empirical basis for the model-dependent links of the solar reaction chains. The CC signal from the model-independent ``pep'' neutrino line is a ``yes/no'' signal for flavor conservation. The shape of the CC $(---pep$)--- line is a direct thermometric probe of the solar core.
