Abstract
As one of the primordial radioactive isotopes, \(^{232}\mathrm{Th}\) mainly undergoes \(\alpha \)-decay with a half-life of \(1.402\cdot 10^{10}\) years. However, it is also one of 35 double beta decay candidates in which the single \(\beta \)-decay is forbidden or strongly suppressed. 181 mg of thorium contained in a gas mantle were measured in a HPGe well-detector at the Gran Sasso Underground Laboratory with a total exposure of 3.25 g\(\times \)d. We obtain half-life limits on all double beta decay modes of \(^{232}\mathrm{Th}\) to excited states of \(^{232}\mathrm{U}\) on the order of \(10^{11-15}\) years. For the most likely transition into the 0\(^+_1\) state we find a lower half-life limit of \(6.7\cdot 10^{14}\) years (90% C.I.). These are the first constraints on double beta decay excited state transition in \(^{232}\mathrm{Th}\).| Reference Key |
