The atomic mass excess of was determined to be -33.419±0.011 MeV for the first time from the measured Q value of -26.919±0.009 MeV for the (αHeAu reaction. The atomic mass excess of was also determined to be -31.080±0.032 MeV by using the known Q value of beta decay to . These results were compared with some predicted values.
