    "abstract": "We have measured the lifetime of the 5s5p ^3P_2 metastable state of strontium\natoms by magneto-optically trapping the decayed atoms to the ground state,\nwhich allowed sensitive detection of the rare decay events. We found that the\nblackbody radiation-induced decay was the dominant decay channel for the state\nat T = 300 K. The lifetime was determined to be 500^{+280}_{-130} s in the\nlimit of zero temperature.",
