ResumoThe $Q$ values of the ($^{3}\mathrm{He}$,$^{6}\mathrm{He}$) reaction on $^{46}\mathrm{Ti}$, $^{50}\mathrm{Cr}$, $^{54}\mathrm{Fe}$, and $^{58}\mathrm{Ni}$ have been measured, and the excitation energy of levels up to 7 MeV has been determined. Angular distributions from the more strongly populated states have been taken from 4.5 to 27.0\ifmmode^\circ\else\textdegree\fi{} in the laboratory. These angular distributions together with comparison to their ${T}_{z}=+\frac{1}{2}$ mirrors have been used as empirical guides to determine the spin and parity of several of the states. The Coulomb displacement energies of particle-hole states in the $T=\frac{1}{2}$ mirrors have been compared to a simple model.NUCLEAR REACTIONS $^{25}\mathrm{Mg}$, $^{27}\mathrm{Al}$, $^{46}\mathrm{Ti}$, $^{50}\mathrm{Cr}$, $^{54}\mathrm{Fe}$, $^{58}\mathrm{Ni}$($^{3}\mathrm{He}$,$^{6}\mathrm{He}$), ${E}_{^{3}\mathrm{He}}=70$ MeV, measured $Q$, $\ensuremath{\sigma}(\ensuremath{\theta})$, excitation energies, obtained mass excess of $^{43}\mathrm{Ti}$, $^{47}\mathrm{Cr}$, $^{51}\mathrm{Fe}$, $^{55}\mathrm{Ni}$, deduced Coulomb displacement energies.
