Solar neutrino interactions with the double beta decay nuclei of $^{82}$Se, $^{100}$Mo and $^{150}$Nd

Solar neutrinos interact within double-beta decay (BB) detectors and contribute to backgrounds for BB experiments. Background contributions due to solar neutrino interactions with BB nuclei of $^{82}$Se, $^{100}$Mo, and $^{150}$Nd are evaluated. They are shown to be significant for future high-sensitivity BB 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 BB experiments.
