Inelastic Deuteron Scattering and (d,p) Reactions from Isotopes of Titanium. III.Ti49(d,p)Ti50

Fifty-six levels in ${\mathrm{Ti}}^{50}$ have been excited by the ($d,p$) reaction on ${\mathrm{Ti}}^{49}$ at 6-MeV bombarding energy. The differential cross sections for the proton groups were measured at 23 scattering angles. A distorted-wave analysis of the experimental results yielded values of the orbital angular momenta of the transferred neutron and transition strengths for 44 of the observed transitions. A sum-rule analysis indicates that all of the $1f_{\frac{7}{2}}$, $2p_{\frac{3}{2}}$, and $2p_{\frac{1}{2}}$ single-particle strengths and 60% of the $1f_{\frac{5}{2}}$ strength were observed. The present data are compared to other experimental evidence on ${\mathrm{Ti}}^{50}$, and a level scheme for ${\mathrm{Ti}}^{50}$ is proposed. The spectroscopic data are discussed in terms of the shell model with residual interactions. The results for the transitions to the ground state and three lowest excited states of ${\mathrm{Ti}}^{50}$ are shown to be in disagreement with seniority conservation.
