Abstract.

An even-odd isotope of ruthenium, 111Ru, is investigated in the framework of the Core-Quasiparticle Coupling model. The energy levels and wave functions of low-lying states are calculated. The only one parameter adjusted to obtain the results in agreement with experimental data is the strength of the core-particle quadrupole-quadrupole interaction. The neighbouring even-even cores, 110Ru and 112Ru, are described by means of the collective “quadrupole plus pairing” model with the Bohr Hamiltonian determined fully from a microscopic theory without any adjustable parameter. Results for 111Ru are compared with a new set of experimental data obtained recently. An importance of the pairing interaction is confirmed. A remarkable agreement of theoretical results and experimental data is obtained for all eight positive- and negative-parity bands delivered by the newest experiment.
