(d, t) Reaction on the Titanium Isotopes

The ($d, t$) reaction on the five stable isotopes of titanium has been studied at a deuteron energy of 21.4 MeV. The three even isotopes show two strong groups separated by about 2 MeV, both groups corresponding to pickup of a $1f_{\frac{7}{2}}$ neutron. This indicates that there is considerable seniority mixing in the titanium isotopes. Groups corresponding to the pickup of $2p$ neutrons were observed in both ${\mathrm{Ti}}^{50}$ and ${\mathrm{Ti}}^{48}$. In the reaction on ${\mathrm{Ti}}^{48}$, an $l=2\mathrm{}$ transition to a state near 1.8 MeV in ${\mathrm{Ti}}^{47}$ was found. The odd-even isotopes show a number of strong groups. The ground-state transitions in ${\mathrm{Ti}}^{48}(d, t){\mathrm{Ti}}^{47}$ and ${\mathrm{Ti}}^{47}(d, t){\mathrm{Ti}}^{46}$ have not been observed.
