In-beam study of 102In, 104In and 106In

Proton-rich odd-odd In isotopes have been investigated by in-beam spectroscopic methods using the NORDBALL detector array. A 58Ni beam with an energy of 270 MeV was used to bombard a 54Fe target. Separtation of different reaction channels was achieved with a 4π charged-particle multi-detector set-up together with a 1π neutron detector wall placed in the forward direction. Excited states of the 102In nucleus were identified for the first time as well as a set of negative-parity states in 104In. In 106In the information about positive- and negative-parity states has been extended. The nuclei are discussed within the framework of the nuclear shell model, the interacting boson-fermion-fermion model and the systematics of the heavier odd-odd indium isotopes.
