Excited states of [Formula Presented] and [Formula Presented] nuclei were populated through the [Formula Presented] and [Formula Presented] reactions, respectively, and investigated by in-beam [Formula Presented]-ray spectroscopic methods. The NORDBALL array equipped with a charged particle ball and 11 neutron detectors was used to detect the evaporated particles and [Formula Presented] rays. The level schemes of [Formula Presented] were constructed on the basis of [Formula Presented]-coincidence relations up to 8.6 and 10 MeV excitation energy, and [Formula Presented] and [Formula Presented] spin and parity, respectively. The structure of [Formula Presented] nuclei was described in the interacting boson-fermion plus broken pair model, including quasiproton, quasiproton-two-quasineutron, and three-quasiproton fermion configurations in the boson-fermion basis states. Most of the states were assigned to quasiparticle + phonon and three quasiparticle configurations on the basis of their electromagnetic decay properties.
