A thin target of magnesium oxide enriched in Mg/sup 24/ was bombarded by 5.52-Mev He/sup 3/ particles. The outgoing neutrons were measured by the method of proton recoils in photographic emulsions. The ground-state Q value of the experiment to be --3.19 plus or minus 0.04 Mev. The Q value of the Mg/sup 24/ (He/sup 3/,n)Si/sup 26/ ground-state reaction is 0.05 plus or minus 0.08 Mev. The mass of Si/sup 26/ is then 25.99232 plus or minus 0.00007 amu (C/sup 12/ standard). In addition, excited states of Si/sup 26/ at 1.75 plus or minus 0.06 and 2.79 plus or minus 0.08 Mev were observed. Angular distributions of these four neutron groups and of the C/sup 12/(He/sup 3/,n)O/sup 14/ ground-state group are also reported; in all but one case, the distributions are peaked in the forward direction.
