Abstract:

Anharmonicity of the two-phonon states in ¹⁰⁰Ru, ¹⁰²Ru and ¹⁰⁴Ru is investigated by means of the selfconsistent-collective-coordinate method. It is shown that the neutron-number dependence of the properties of the 0₂⁺ states can be reproduced by renormalizing the coupling effect of the neutron pairing vibrations into the collective Hamiltonian for quadrupole vibrations.
