Abstract
The value for the reaction has been measured by observing the recoil ions in a magnetic spectrometer at 10-MeV bombarding energy. Observations at 1.7° and 7.0° laboratory angle yield MeV, based on the ThC' alpha line at 8.7841 MeV. The - mass difference computed from this value corresponds to an endpoint energy of 16.320 MeV for the beta decay and a value of (1.29±0.02)×. The ratio becomes 1.10±0.02.
