Conflicting coupling of the unpaired nucleons and the structure of collective bands in odd-odd nuclei

Conflicting coupling of unpaired nucleons in the odd-odd nuclei is discussed. A very simple explanation is suggested for the damping of the energy spacing of the lowest levels in the rotational bands in the odd-odd nuclei in the case of a "conflicting" coupling of the odd proton and neutron comparative to those of the bands based on the state of the strongly-coupled particle in the neighbouring odd nuclei entering the "conflicting" configuration.

Electromagnetic E2 transition probabilities in 120Xe and 118Te - N=66 nuclei

Lifetimes of the yrast states in 120Xe and ground state band below and above band crossing in 118Te have been measured by DSAM in the 111Cd(12C,3n) reaction and by DSAM and RDM in the 109Ag(13C,p3n) reaction, respectively. The results are compared with E2 transition probabilities in 119I and 128Ba. The experimental data are compared with calculation done in the framework of the IBM1 model in the O(6) and SU(5) limits.
