The time-of-flight and slow-neutron threshold techniques in conjunction with He/sup 3/ particles of energies of up to 11 Mev, were used to measure the Q value of the O/sup 14/(He/sup 3/,n) Ne/sup 18/ reaction and to locate levels in O/ sup 14/ and Ne/sup 18/. The Q value, -3.199 plus or minus 0.006 Mev, requires a mass defect of 10.649 plus or minus 0.008 Mev for Ne/sup 18/. Levels were found in O/sup 14/ at 5.905 plus or minus 1.880 plus or minus 0.010, 3.362 plus or minus 0.011, and 3.608 plus or minus 0.012 Mev. Excitation functions are measured between 2.0 and 5.7 Mev for both reactions. Angular distributions of the C/sup 12/(He/sup 3/,n) reaction measured at 4.65, 4.96 and 5.26 Mev, are compared with theory for a double stripping process. The data suggest that a direct process is competing strongly with compound nucleus formation in this energy region. (auth)
