Study of the Level Structure ofTi48Using theTi47(n, γ)Reaction

The capture $\gamma$-ray spectrum resulting from thermal-neutron capture in ${}_{}{}^{47}{}_{}{}^{}\mathrm{Ti}$ has been measured using a 30-${\mathrm{cm}}^3$ Ge(Li) detector and angular-correlation measurements carried out using NaI(Tl) detectors. Some 28 $\gamma$ lines corresponding to transitions between levels of ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}$ were observed, and the neutron separation energy of ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}$ was determined to be 11.630±0.008 MeV. The following assignments of spins and parities for some levels were made: 2.422($1^{+}$, $2^{+}$, $3^{+}$), 3.626($2^{+}$, $4^{+}$), 3.794($2^{+}$, $3^{+}$, $4^{+}$), and 4.467($2^{+}$, $3^{+}$). The results of a comparison between the measured strengths of exciting the ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}$ levels in the ($n, \gamma$) and ($d, p$) reactions are discussed.
