Collective model of odd-odd deformed nuclei

A model of odd-odd nuclei, in which two odd nucleons are attached to a rotating core, is described. The Hamiltonian consists of HR, the rotational part, Hp and Hn, the. Hamiltonians for proton and neutron moving in harmonic oscillator potential wells with ℓ.s and ℓ2 terms, Vpn , the residual neutron-proton interaction which has a Gaussian radial dependence with a Serber exchange mixture. The model is applied to all the main odd-odd nuclei whose energy spectra are experimentally known. The present investigation deals with all the main odd-odd nuclei on the basis of symmetric and asymmetric core models.
