Electrostatic Analysis of Nuclear Reaction Energies. II

Electrostatic analysis of incident and product particle energies has been used to measure the following ground state $Q$-values: ${\mathrm{O}}^{16}(d,\alpha ){\mathrm{N}}^{14}$ (3.113±0.0035 Mev), ${\mathrm{B}}^{10}\left(p{\mathrm{He}}^3\right){\mathrm{Be}}^8$ (-0.0536±0.003 Mev), and ${\mathrm{B}}^{10}(p,\alpha ){\mathrm{Be}}^7$ (1.147±0.0025 Mev). The energy of the lowest level in ${\mathrm{B}}^{10}$ has been determined to be 719±1.6 kev; that of ${\mathrm{Be}}^7$ to be 429±3 kev. Approximate cross sections are given for the above reactions and upper limits for ${\mathrm{O}}^{16}(d,\alpha ){\mathrm{N}}^{14*}$ (2.3-Mev level), and for ${\mathrm{B}}^{10}(p,p^{\prime }){\mathrm{B}}^{10*}$ (2.1- and 1.7-Mev levels).
