摘要：

High-spin states in the nuclei Ti-47, V-47, Cr-47, V-48, and Cr-48 have been observed using the reaction Ca-40 + B-10 at E(Ca-40)=150 MeV. The prompt gamma rays were detected in an array of 19 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 Ti-47, up to spins near the maximum for the (f7/2)z+n configuration. A rapid increase in the Coulomb displacement energy for mirror states in V-47 and Cr-47 occurs at J(pi) = 25/2-. A backbend occurs in Cr-48 at J(pi) = 10+.
