Abstract The lifetimes τ=124±12, 6 −2 +4 and 380±100 ps of theE x (I π )=3.46(8+), 2.92(6+) and 3.04(6−) MeV states, respectively, populated by the reaction76Ge(12C,α2n) were measured with the recoil distance method. In addition upper lifetime limits were obtained for nine states. The measured lifetimes and energies indicate a band crossing at aboutI π =8+, probably arising from the alignment of twog 9/2 neutrons. For the 3.04 MeV 6− state as a second member of a band built on the 2.65 MeV 4− state the measured lifetime points to a two-quasiparticle configuration. The positive-parity states have been discussed in the frame of the interacting boson approximation, nuclear field theory and the cranked shell model.
