Abstract

Bi209 alpha decay to the ground and to the first excited state have been recently observed for the first time with a large BGO scintillating bolometer. The half-life of Bi209 is determined to be τ1/2=(2.01±0.08)×1019   yr while the branching ratio for the ground-state to ground-state transition is (98.8±0.3)%.
