High-spin states inV48,Cr51, andMn51

The reactions ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ ${+}^{14}$N at ${\mathit{E}}_{\mathrm{N}}$=40 MeV and ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$ ${+}^{27}$Al at ${\mathit{E}}_{\mathrm{Al}}$=90 MeV are used to populate high-spin levels in a number of ${\mathit{f}}_{7/2}$ nuclei, from ${}_{}{}^{45}{}_{}{}^{}\mathrm{Sc}$ to ${}_{}{}^{52}{}_{}{}^{}\mathrm{Fe}$. In ${}_{}{}^{51}{}_{}{}^{}\mathrm{Cr}$, the ${\mathit{f}}_{7/2}$ band-terminating state at ${\mathit{J}}^{\mathrm{\pi }}$=23/$2^{\mathrm{-}}$ is identified at 5.711 MeV, and further transitions, from the pf band, are found. Similar evidence for interband transitions in ${}_{}{}^{51}{}_{}{}^{}\mathrm{Mn}$ is sought without success. In ${}_{}{}^{48}{}_{}{}^{}\mathrm{V}$, new transitions are found within the positive-parity band and between the negative- and positive-parity bands.
