Neutrino Mass Search with Single Ba+ Ion Detection
Abstract
A new method to search for the neutrino mass is being developed: zero neutrino double beta decay efficient 136Ba+ daughter ion tagging by laser induced fluorescence in a liquid Xe time-projection chamber. We report new measurements of the fluorescence spectrum of Ba+ in liquid Xe using a spectrometer with liquid nitrogen cooled CCD camera. We also use the CCD camera to capture a real time fluorescence image of the Ba+ ion cloud and determine the survival time of the Ba+ ions. New results are presented for the mobility of Ba+, Tl+, Mg+, Ca+, and Sr+ in liquid Xe.
