Recoil-separated gamma-ray spectroscopy ofTi47,V47,Cr47,V48, andCr48

High-spin states in the nuclei ${}_{}{}^{47}{}_{}{}^{}\mathrm{Ti}$, ${}_{}{}^{47}{}_{}{}^{}\mathrm{V}$, ${}_{}{}^{47}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{48}{}_{}{}^{}\mathrm{V}$, and ${}_{}{}^{48}{}_{}{}^{}\mathrm{Cr}$ have been observed using the reaction ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ ${+}^{10}$B at E${(}^{40}$Ca)=150 MeV. The prompt γ rays were detected in an array of nineteen escape-suppressed Ge detectors in coincidence with the recoiling nuclei which were identified in A and Z with a recoil separator. Rotational structures were observed in all these nuclei, apart from ${}_{}{}^{47}{}_{}{}^{}\mathrm{Ti}$, up to spins near the maximum for the (${\mathit{f}}_{7/2}$ ${)}^{\mathit{z}+\mathit{n}}$ configuration. A rapid increase in the Coulomb displacement energy for mirror states in ${}_{}{}^{47}{}_{}{}^{}\mathrm{V}$ and ${}_{}{}^{47}{}_{}{}^{}\mathrm{Cr}$ occurs at ${\mathit{J}}^{\mathrm{\pi }}$=25/$2^{\mathrm{-}}$. A backbend occurs in ${}_{}{}^{48}{}_{}{}^{}\mathrm{Cr}$ at ${\mathit{J}}^{\mathrm{\pi }}$=${10}^{+}$.
