Imaging of single barium atoms in a second matrix site in solid xenon for barium tagging in a ^{136}Xe double beta decay experiment

Neutrinoless double beta decay is one of the most sensitive probes for new physics beyond the Standard Model of particle physics. One of the isotopes under investigation is ^{136}Xe, which would double beta decay into ^{136}Ba. Detecting the single ^{136}Ba daughter provides a sort of ultimate tool in the discrimination...
