Effects of the particle-particle channel on properties of low-lying vibrational states
A. P. Severyukhin, V. V. Voronov, Nguyen Van Giai
Making use of the finite rank separable approach for the quasiparticle random phase approximation enables one to perform nuclear structure calculations in very large two-quasiparti…
Large-amplitude Qn-Qp collectivity in the neutron-rich oxygen isotope 20O
A. P. Severyukhin, M. Bender, H. Flocard +1
By means of HFB calculations with independent constraints on axial neutron and proton quadrupole moments Q_n and Q_p, we investigate the large amplitude isoscalar and isovector def…
Beyond mean-field study of excited states: Analysis within the Lipkin model
A. P. Severyukhin, M. Bender, P. -H. Heenen
Beyond mean-field methods based on restoration of symmetries and configuration mixing by the generator coordinate method (GCM) enable to calculate on the same footing correlations…
Effects of phonon-phonon coupling on low-lying states in neutron-rich Sn isotopes
A. P. Severyukhin, V. V. Voronov, Nguyen Van Giai
Starting from an effective Skyrme interaction we present a method to take into account the coupling between one- and two-phonon terms in the wave functions of excited states. The a…
Nuclear structure calculations with a separable approximation for Skyrme interactions
A. P. Severyukhin, V. V. Voronov, Ch. Stoyanov +1
A finite rank separable approximation for the quasiparticle RPA calculations with Skyrme interactions that was proposed in our previous work is extended to take into account the co…
Separabelized Skyrme Interactions and Quasiparticle RPA
A. P. Severyukhin, V. V. Voronov, Ch. Stoyanov +1
A finite rank separable approximation for the quasiparticle RPA with Skyrme interactions is applied to study the low lying quadrupole and octupole states in some S isotopes and gia…
