Selena is a proposed experiment to search for the neutrinoless ?? decay of Se-82 with a large number of hybrid CMOS-amorphous selenium imaging sensors. Se-82 is also an interesting target for solar neutrinos since its low-energy threshold for electron-neutrino capture (172 keV) provides access to all solar neutrino species. The reaction product is a Br-82 isomer that undergoes a sequence of two decays into stable Kr-82, which provides a unique signature for solar neutrino capture. This may allow Selena to perform precision solar neutrino spectroscopy with zero background to measure the neutrino luminosity, core temperature and metallicity of the Sun.
