Electrostatic analysis of incident and product particles has been used to measure the following reaction energies (in Mev): $\mathrm{D}(d, {\mathrm{H}}^3)p$ (4.044±0.005); $\mathrm{D}(d, {\mathrm{He}}^3)n$ (3.271±0.011); ${\mathrm{C}}^{14}(d, \alpha ){\mathrm{B}}^{12}$ (0.362±0.002); ${\mathrm{C}}^{14}(d, p){\mathrm{C}}^{15}$ (-1.007±0.001); ${\mathrm{B}}^{10}(\alpha , d){\mathrm{C}}^{12}$ (1.341±0.002); ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17*}$, 0.87 level (1.048±0.002); ${\mathrm{N}}^{14}(d, p){\mathrm{N}}^{15*}$, 7.31 level (1.308±0.002); 7.58 level (1.045±0.002); 8.32 level (0.296±0.001) and 8.57 level (0.038±0.001); ${\mathrm{C}}^{12}(d, p){\mathrm{C}}^{13*}$ 3.68 level (-0.960±0.002) and 3.86 level (-1.130±0.002) and ${\mathrm{N}}^{14}(d, \alpha ){\mathrm{C}}^{12*}$ 9.6 level (3.933±0.014). The 30-kev width of the 9.6-Mev level of ${\mathrm{C}}^{12}$ limits the spin and parity assignment to $0^{+}$, $1^{-}$, $2^{+}$, or $3^{-}$, or possibly $4^{+}$.
