Investigation of the (d,p) and (d,α) Reactions of the Silicon Isotopes

An investigation of the ${\mathrm{Si}}^{29}(d,\alpha ){\mathrm{Al}}^{27}$, ${\mathrm{Si}}^{29}\mathrm{}(d,p)\mathrm{}{\mathrm{Si}}^{30}$, and ${\mathrm{Si}}^{30}\mathrm{}(d,p)\mathrm{}{\mathrm{Si}}^{31}$ reactions has been made using a high resolution magnetic spectrograph. The spectra of particle groups observed at 90 degrees to the incident deuteron beam from silicon-dioxide targets enriched in ${\mathrm{Si}}^{29}$ and ${\mathrm{Si}}^{30}$ were compared to the spectra obtained from targets of natural ${\mathrm{SiO}}_2$. The $Q$-values for the ground-state transitions are 5.994±0.011, 8.388±0.013, and 4.364±0.007 Mev. The following level positions have been determined: $\{{\mathrm{Al}}^{27},:0.84\mathrm{a}\mathrm{n}\mathrm{d}1.01\mathrm{M}\mathrm{e}\mathrm{v}.\}\{{\mathrm{Si}}^{30},:2.24,3.51,\mathrm{a}\mathrm{n}\mathrm{d}3.79\mathrm{M}\mathrm{e}\mathrm{v}.\}\{{\mathrm{Si}}^{31},:0.757,1.699,2.319,2.751,3.140,3.539,\mathrm{a}\mathrm{n}\mathrm{d}4.384\mathrm{M}\mathrm{e}\mathrm{v}.\}$
