Radiochemical experiments for low-energy solar-neutrino detection have been making headlines by exploiting
the isotopes 37Cl and 71Ga. Such a very low-threshold measurement of this type can also be performed using 205Tl, which has been considered for decades for this purpose. A unique feature of this detector nucleus is the
integration in the solar-neutrino flux over 106 of years owing to its long-living daughter 205Pb. In this Rapid
Communication, we have calculated for the first time the cross section for the charged-current solar-neutrino
scattering off 205Tl. Taking into account the solar-model-predicted neutrino fluxes and the electron-neutrino
survival probabilities, a solar-neutrino capture rate of 62.2 ± 8.6 solar-neutrio units is determined, a value
significantly smaller than in previous estimates.

Solar neutrino detection in liquid xenon detectors via charged-current scattering to excited states
Haselschwardt, Scott; Lenardo, Brian; Pirinen, Pekka; Suhonen, Jouni (American Physical Society (APS), 2020)We investigate the prospects for real-time detection of solar neutrinos via the charged-current neutrino-nucleus scattering process in liquid xenon time projection chambers. We use a nuclear shell model, benchmarked with ... -
Neutral-current supernova-neutrino cross sections for 204,206,208Pb calculated by Skyrme quasiparticle random-phase approximation
Almosly, Wafa; Carlsson, B. G.; Suhonen, Jouni; Ydrefors, E. (American Physical Society, 2019)The present work constitutes a detailed study of neutral-current (NC) supernova-neutrino scattering off the stable even-even lead isotopes 204,206,208Pb. This is a continuation of our previous work [Almosly et al., Phys. ... -
Improved calculations of β decay backgrounds to new physics in liquid xenon detectors
Haselschwardt, S. J.; Kostensalo, J.; Mougeot, X.; Suhonen, J. (American Physical Society (APS), 2020)We present high-precision theoretical predictions for the electron energy spectra for the ground-state to ground-state β decays of 214Pb, 212Pb, and 85Kr most relevant to the background of liquid xenon dark matter detectors. ... -
Estimated solar-neutrino capture rates of 131Xe : implications for multi-tonne Xe-based experiments
Kostensalo, J.; Suhonen, J.; Zuber, K. (Institute of Physics, 2021)Various large-scale experiments for double beta decay or dark matter are based on xenon. Current experiments are on the tonne scale, but future ideas also aim for even larger sizes. Here we study the potential of the isotope ... -
Analysis of light neutrino exchange and short-range mechanisms in 0νββ decay
Deppisch, Frank F.; Graf, Lukas; Iachello, Francesco; Kotila, Jenni (American Physical Society (APS), 2020)Neutrinoless double beta decay (0νββ) is a crucial test for lepton number violation. Observation of this process would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. ...
