Polarization effects in superdeformed nuclei
(1998) In Nuclear Physics A 639(3-4). p.654-682- Abstract
A detailed theoretical investigation of polarization effects in superdeformed nuclei is performed. In the pure harmonic oscillator potential it is shown that when one particle (or hole) with the mass single-particle quadrupole moment qν is added to a superdeformed core, the change of the electric quadrupole moment can be parameterized as qeff = e(bqν + a), and analytical expressions are derived for the two parameters, a and b. Simple numerical expressions for qeff(qν) are obtained in the more realistic modified oscillator model. It is also shown that quadrupole moments of nuclei with up to 10 particles removed from the superdeformed core of 152Dy can be well described by... (More)

Simple numerical expressions for qeff(qν) are obtained in the more realistic modified oscillator model. It is also shown that quadrupole moments of nuclei with up to 10 particles removed from the superdeformed core of 152Dy can be well described by simply subtracting effective quadrupole moments of the active single-particle states from the quadrupole moment of the core. Tools are given for estimating the quadrupole moment for possible configurations in the superdeformed A ∼ 150 region.
