“…As a function of J z , the neutron et proton routhians we obtained are quite similar to those obtained with cranked Wood-Saxon methods [37], although the assignment of Nilsson quantum numbers to our orbitals is not always unambiguous, as discussed in [38] Experimentally, one SD band has been observed in 192 Hg [39,40] Hg band. By discrete differentiation of J z with respect tohω, we have calculated the dynamical moment of inertia J 2 of these bands as a function of J z .…”

An overview of a microscopic framework based on the Hartree-Fock description of the mean field is presented which, starting from an effective interaction allows a description of collective motions. A study of the isotope shifts in the Pb region illustrates the importance of the effective interactions and points to their limitations. Such forces should be improved in order to achieve a better description of nuclei properties especially with the coming availability of exotic beam facilities. The coupling of collective quadrupole and octupole degrees of freedom in 194 Pb is analyzed within the Generator Coordinate Method, which represents a step beyond the simple mean-field approximation. As a last example, we present a study of nuclear rotations. First we discuss results on superdeformed rotating bands in 192 Hg, 194 Hg and 194 Pb obtained without including a treatment of pairing correlations. Preliminary calculations are also presented with these correlations included as well as an approximate projection on nucleon number. THEORETICAL OUTLINETwo types of basic ingredients can be found in most mean field calculations; first a twobody nucleon-nucleon effective interaction, such as a Skyrme-type one, complemented by a pairing interaction. The many body wave function representing the nucleus is approximated by a Slater determinant or a BCS state. Then a minimization of its energy yields

“…For simplicity we present here only threefour significative digits in each parameter, it is less than is necessary to reproduce four digits in transition energy. It may be useful to note that by the value of the parameter •' we can determine 7 pairs of bands with practically the same value of this parameter: (3,6). These bands which were also paired in the work [23], correspond to the same intrinsic structure.…”

Abstract. The triplet pairing model, which has been shown, in some cases, to be equivalent to the cranking and/or variable moment of inertia models, is used to describe the superdeformed bands in AN 190 region. The two-parameter expression for the 7-transition energies E~(I), common to these three models, allows a good description of experimental data and an unambiguous spin assignment for the states of these superdeformed bands.

“…Before discussing this behavior we will look at the data from other nuclei in this region. A large number of new superdeformed bands have recently been found in the mass-190 region (189Jlg [9], 190Jfg [10], 191Hg [11,12], 192flg [6,13], 193Hg [14,15], 194Hg [16,17], 193TI [9], 19411 [18],194Pb[l9,20], and 196Pb [19]. Many of these bands are related to the band in 192flg as were the bands in I94Hg discussed above.…”
