Ti46,48(d, p)Ti47,49Reactions and the1f72nand1f72n−12pConfigurations

The nuclide ${\mathrm{Ti}}^{47}$ was investigated via a high-resolution spectroscopic study of the reaction ${\mathrm{Ti}}^{46}(d, p){\mathrm{Ti}}^{47}$. The observed levels, the measured orbital angular momenta of the captured neutrons, and the tentative total angular momenta assigned on the basis of relative intensities were as follows: ground state, 0.16 Mev, $l_n=3\mathrm{}$, $J^{\pi }={\frac{7}{2}}^{-}$; (0.55 Mev, $J^{\pi }={\frac{3}{2}}^{-}$); 1.56 Mev, $l_n=1\mathrm{}$, ($J^{\pi }={\frac{3}{2}}^{-}$); 1.80 Mev, $l_n=1\mathrm{}$, ($J^{\pi }={\frac{3}{2}}^{-}$); 2.58 Mev, $l_n=1\mathrm{}$; 2.83 Mev, $l_n=1\mathrm{}$; 3.31 Mev, $l_n=1\mathrm{}$, ($J^{\pi }={\frac{1}{2}}^{-} or {\frac{3}{2}}^{-}$); 3.60 Mev, ($l_n=1\mathrm{}$, $J^{\pi }={\frac{1}{2}}^{-}$); 3.71 Mev, ($l_n=1\mathrm{}$, $J^{\pi }={\frac{1}{2}}^{-}$); and 3.95 Mev, ($l_n=1\mathrm{}$, $J^{\pi }={\frac{1}{2}}^{-}$). Similarly for ${\mathrm{Ti}}^{49}$: ground state, $l_n=3\mathrm{}$, $J^{\pi }={\frac{7}{2}}^{-}$; 1.38 Mev, $l_n=1\mathrm{}$, $J^{\pi }={\frac{3}{2}}^{-}$; 1.72 Mev, $l_n=1\mathrm{}$, ($J={\frac{3}{2}}^{-}$); 2.44 Mev; 2.49 Mev; 3.17 Mev, ($l_n=1\mathrm{}$, $J^{\pi }={\frac{1}{2}}^{-}$); and 3.26 Mev, $l_n=1\mathrm{}$, ($J^{\pi }={\frac{1}{2}}^{-}$). It is shown that the ground state of ${\mathrm{Ti}}^{49}$ and the ground-state triplet of ${\mathrm{Ti}}^{47}$ can be accounted for by pure ${f_{\frac{7}{2}}}^n$ configurations, and that most of the observed levels can be associated with $1{f_{\frac{7}{2}}}^{n-1\mathrm{}}2p_{\frac{3}{2}}$ and $1{f_{\frac{7}{2}}}^{n-1\mathrm{}}2p_{\frac{1}{2}}$ configurations.
