Excited states in 110I have been identified for the first time using the αpn evaporation channel from the 58Ni+58Ni reaction at a beam energy of 250 MeV. The experiment was carried out using GAMMASPHERE coupled to the MICROBALL charged-particle detector array and an array of 15 neutron detectors. Two collective structures were observed with the yrast band built on the πh11/2⊗νh11/2 configuration. Comparisons of the yrast-band energies with the excitation energies of the yrast states in even 52Te and in odd 52Te and 53I isotopes for A ∼ 110 were analyzed, revealing different responses of the underlying cores to the valence πh11/2 and νh11/2 orbitals. It is concluded that the neutron h11/2 valence orbital has a larger influence than that of the proton h11/2 valence orbital.
