- The nucleus Cd-110 has been studied using the C-13 and O-18 induced reactions and the NORDBALL multi-detector array. The yrast band was observed to I(pi) = 28+ and a large number of side bands were identified. The h11/2 neutrons were found to play a dominant role in the observed rotational structures. The weakly populated yrast 3187 keV 8+ state is interpreted as arising from the proton g9/2(-2) configuration. Collective bands, where the band members are connected by DELTAI = 1 transitions and where the DELTAI = 2 transitions are not observed, are also reported. These bands are interpreted to have prolate configurations involving both the h11/2 neutrons and the g9/2 protons. The experimental data are discussed in terms of the total routhian surface and cranked shell model calculations.

- Excited states in the doubly odd nucleus Rb-80 have mainly been studied via the Zn-68(F-19,alpha3n) reaction at 72 MeV beam energy utilizing the NORDBALL detector system. The level scheme has been extended up to a (15+) state at 4446 keV excitation energy. In the low-spin region seven new isomers with lifetimes in the nanosecond region have been found. In addition, a 6+ isomer with a half-life of the order of mus has been identified at an excitation energy of 494.4 keV. For the level sequence built on this isomer positive parity is suggested and the states are ascribed to the intruder two-quasiparticle configuration (pig9/2 x nug9/2) and collective excitations.
