Deuteron Stripping and Pickup Reactions in Oxygen-16

The reactions ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17}$ and ${\mathrm{O}}^{16}(d, t){\mathrm{O}}^{15}$ were studied by bombarding thin nickel oxide foils with 15-Mev deuterons from the University of Pittsburgh cyclotron. The reaction particles were magnetically analyzed and detected either by nuclear emulsions or by a CsI(Tl) scintillator. Angular distributions and absolute cross sections were obtained for the first six states of ${\mathrm{O}}^{17}$ and for the ground state of ${\mathrm{O}}^{15}$. Reduced widths having values ${\ominus }^2=0.045, 0.16, 0.0024, 0.0024, 0.0071, 0.047, \mathrm{and} 0.012$, respectively, were extracted from a comparison of the data with the predictions of Butler stripping theory. The most notable results of the ($d, p$) experiment indicate that: (1) the ${\frac{7}{2}}^{-}$ state at 3.846 Mev does not appear to be a good $1f_{\frac{7}{2}}$ single-particle state, (2) the $2p_{\frac{3}{2}}$ single-particle component seems to be fragmented over more than two states, and (3) the ${\mathrm{½}}^{-}$ state at 3.058 Mev contains a $2p_{\frac{1}{2}}$ single-particle component. The results of the ($d, t$) experiment suggest a dependence of the $1p$ single-particle reduced width on $Q$ value.
