Solar neutrino interactions with the double-β decay nuclei 82Se, 100Mo, and 150Nd

Solar neutrinos interact within double-beta decay (beta) detectors and contribute to backgrounds for beta beta experiments. Background contributions due to solar neutrino interactions with beta beta nuclei of Se-82, Mo-100, and Nd-150 are evaluated. They are shown to be significant for future high-sensitivity beta beta experiments that may search for Majorana neutrino masses in the inverted-hierarchy mass region. The impact of solar neutrino backgrounds and their reduction are discussed for future beta beta experiments.
