Abstract

Rotational bands based on intrinsic wave functions with a pure two-quasiparticle structure in deformed even-mass nuclei are investigated within the framework of constraint Hartree-Fock-Bogolyubov theory. Selfconsistency is achieved from the variation principle with the additional constraint of orthogonality to the yrast wave function. In the nucleus 164Er various semidecoupled and completely decoupled bands are discussed. The calculated spectra are in fair agreement with experiment.

    The effects of blocking due to the odd particle were included in a fully self-consistent way. This was done within the code CRHB, according to Refs. [58–60]. The blocked orbital was specified by different tags such as (i) dominant main oscillator quantum number N of the wave function, (ii) dominant Ω quantum number of the wave function, (iii) particle or hole nature of the blocked orbital, and (iv) position of the state within the specific parity/signature/dominant-N/dominant-Ω.

    In this context, the basis of a harmonic oscillator (HO) turned out to be particularly useful. Over the years, many configuration-space HFB+HO codes have been developed, either employing Skyrme forces or the Gogny effective interaction [12–16], or using a relativistic Lagrangian [17] in the context of the relativistic Hartree–Bogolyubov theory. For nuclei at the drip lines, however, the HFB+HO expansion converges slowly as a function of the number of oscillator shells [3], producing wave functions that decay too rapidly at large distances.
