Abstract

The Q value for the reaction B10(He3, N12)n has been measured by observing the (N12)5+ recoil ions in a magnetic spectrometer at 10-MeV bombarding energy. Observations at 1.7° and 7.0° laboratory angle yield Q=1.570±0.025 MeV, based on the ThC' alpha line at 8.7841 MeV. The N12-C12 mass difference computed from this Q value corresponds to an endpoint energy of 16.320 MeV for the N12 beta decay and a ft value of (1.29±0.02)×10^4. The ratio ft(N12)/ft(B12) becomes 1.10±0.02.
