q-deformed pairing vibrations.
Boson creation operators constructed from linear combinations of qdeformed zero coupled nucleon pair operators acting on the nucleus (A,0), are used to derive pp-RPA equations. The solutions of these equations are the pairing vibrations in (A+2) nuclei. For the 01 and 0 + 2 states of the nucleus 208Pb, the variations of relative energies and transfer cross-sections for populating these states v...
متن کاملPairing - correlations and particle - number projection methods
A systematic study of the pairing-correlations derived from various particle-number projection methods is performed in an exactly soluble cranked-deformed shell model Hamiltonian. It is shown that most of the approximate particle-number projection methods including the method of Lipkin-Nogami, which is used quite extensively in nuclear structure studies, breakdown in the weak pairing limit. The...
متن کاملStudy of Giant Pairing Vibrations with neutron-rich nuclei
We investigate the possible signature of the presence of giant pairing states at excitation energy of about 10 MeV via two-particle transfer reactions induced by neutron-rich weakly-bound projectiles. Performing particle-particle RPA calculations on Pb and BCS+RPA calculations on Sn, we obtain the pairing strength distribution for two particles addition and removal modes. Estimates of two-parti...
متن کاملQuasi-Particle and collective magnetism: Rotation, pairing and blocking in high-K isomers
For the first time, a wide range of collective magnetic g-factors gR, obtained from a novel analysis of experimental data for multi-quasiparticle configurations in high-K isomers, is shown to exhibit a striking systematic variation with the relative number of proton and neutron quasiparticles, Np Nn. Using the principle of additivity, the quasi-particle contribution to magnetism in high-K isome...
متن کاملPolynomials for Ate Pairing and Atei Pairing
The irreducible factor r(x) of Φk(u(x)) and u(x) are often used in constructing pairing-friendly curves. u(x) and uc ≡ u(x) (mod r(x)) are selected to be the Miller loop control polynomial in Ate pairing and Atei pairing. In this paper we show that when 4|k or the minimal prime which divides k is larger than 2, some u(x) and r(x) can not be used as curve generation parameters if we want Atei pa...
