High-spin [(πf72)2(νf72)−1] configuration, two-particle—one-hole states inTi49

The ${}_{}{}^{51}{}_{}{}^{}\mathrm{V}(\overrightarrow{\mathrm{d}},\alpha ){}_{}{}^{49}{}_{}{}^{}\mathrm{Ti}$ reaction has been studied with 79.4-MeV vector polarized deuterons. Angular distributions of the differential cross section and vector analyzing power have been measured for strongly-populated states up to an excitation energy of 5 MeV. Two-particle—one-hole states of the [${\left(\pi f_{\frac{7}{2}}\right)}^2{\left(\nu f_{\frac{7}{2}}\right)}^{-1\mathrm{}}$] configuration were identified from the characteristic $L=6\mathrm{}$ shapes of the differential cross section and $J=7\mathrm{}$ patterns of the vector analyzing power. These states lie at 0.00, 1.54, 1.62, 2.26, 2.72, 2.98, 3.05, 3.29, 3.46, 3.97, 4.22, and 4.39 MeV in ${}_{}{}^{49}{}_{}{}^{}\mathrm{Ti}$. The relative ${\left(f_{\frac{7}{2}}\right)}_{J=7\mathrm{}}^2$ pickup strength to these states is compared to predictions of the ${\left(f_{\frac{7}{2}}\right)}^n$ model of Kutschera, Brown, and Ogawa. The identification in this work of [${\left(\pi f_{\frac{7}{2}}\right)}^2{\left(\nu f_{\frac{7}{2}}\right)}^{-1\mathrm{}}$] configuration states at 4.39 and 3.97 MeV tends to confirm the suggestion that states found at 4.4 and 4.0 MeV in the ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}(\mathrm{p},{\pi }^{-}){}_{}{}^{49}{}_{}{}^{}\mathrm{Ti}$ reaction are the ${\frac{19}{2}}^{-}$ and ${\frac{15}{2}}^{-}$ members of that configuration.
