Bohr Hamiltonian with deformation-dependent mass term

Dennis Bonatsos, P. Georgoudis, D. Lenis +2

The Bohr Hamiltonian describing the collective motion of atomic nuclei is modified by allowing the mass to depend on the nuclear deformation. Exact analytical expressions are deriv…

Green's function method for strength function in three-body continuum

Y. Suzuki, W. Horiuchi, D. Baye

Practical methods to compute dipole strengths for a three-body system by using a discretized continuum are analyzed. New techniques involving Green's function are developed, either…

Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. XI: Stabilizing neutron stars against a ferromagnetic collapse

N. Chamel, S. Goriely, J. M. Pearson

We construct a new Hartree-Fock-Bogoliubov (HFB) mass model, labeled HFB-18, with a generalized Skyrme force. The additional terms that we have introduced into the force are densit…

Probing the weakly-bound neutron orbit of Ne with total reaction and one-neutron removal cross sections

W. Horiuchi, Y. Suzuki, P. Capel +1

A candidate of a neutron-halo nucleus, Ne, contains a single neutron in the shell. Within the Glauber and eikonal models, we analyze reactions used to study Ne.…

Recent breakthroughs in Skyrme-Hartree-Fock-Bogoliubov mass formulas

S. Goriely, N. Chamel, J. M. Pearson

We review our recent achievements in the construction of microscopic mass tables based on the Hartree-Fock-Bogoliubov method with Skyrme effective interactions. In the latest of ou…

Tensor part of the Skyrme energy density functional. II: Deformation properties of magic and semi-magic nuclei

M. Bender, K. Bennaceur, T. Duguet +3

We study systematically the impact of the time-even tensor terms of the Skyrme energy density functional, i.e. terms bilinear in the spin-current tensor density, on deformation pro…

Influence of low energy scattering on loosely bound states

Jean-Marc Sparenberg, Pierre Capel, Daniel Baye

Compact algebraic equations are derived, which connect the binding energy and the asymptotic normalization constant (ANC) of a subthreshold bound state with the effective-range exp…

Extended Skyrme interaction (II): ground state of nuclei and of nuclear matter

Jérôme Margueron, Stéphane Goriely, Marcella Grasso +2

We study the effect of time-odd components of the Skyrme energy density functionals on the ground state of finite nuclei and in nuclear matter. The spin-density dependent terms, wh…

Skyrme-Hartree-Fock-Bogoliubov nuclear mass formulas: Crossing the 0.6 MeV threshold with microscopically deduced pairing

S. Goriely, N. Chamel, J. M. Pearson

We present a new Skyrme-Hartree-Fock-Bogoliubov nuclear-mass model in which the contact-pairing force is constructed from microscopic pairing gaps of symmetric nuclear matter and n…
