The high-spin structure of [Formula Presented] has been studied through the [Formula Presented] reaction at a beam energy of 220 MeV. The level scheme has been extended up to an excitation energy of 11.9 MeV. Four collective structures have been identified based on two-quasineutron configurations. The low-lying states of both parities, as well as the main [Formula Presented] regular structures observed at high spin, are described in the framework of the interacting boson-fermion model with broken pairs.
