Nuclear matter response function with a central plus tensor Landau interaction

A. Pastore, D. Davesne, J. Navarro

We present a method to obtain response functions in the random phase approximation (RPA) based on a residual interaction described in terms of Landau parameters with central plus t…

Nuclear energy density optimization: Shell structure

M. Kortelainen, J. McDonnell, W. Nazarewicz +8

Nuclear density functional theory is the only microscopical theory that can be applied throughout the entire nuclear landscape. Its key ingredient is the energy density functional.…

Spurious finite-size instabilities in nuclear energy density functionals

V. Hellemans, A. Pastore, T. Duguet +5

It is known that some well-established parametrizations of the EDF do not always provide converged results for nuclei and a qualitative link between this finding and the appearance…

Probing pairing correlations in Sn isotopes using Richardson-Gaudin integrability

Stijn De Baerdemacker, Veerle Hellemans, Rianne van den Berg +5

Pairing correlations in the even-even A=102-130 Sn isotopes are discussed, based on the Richardson-Gaudin variables in an exact Woods-Saxon plus reduced BCS pairing framework. The…

NACRE II: an update of the NACRE compilation of charged-particle-induced thermonuclear reaction rates for nuclei with mass number

Yi Xu, Kohji Takahashi, Stephane Goriely +3

An update of the NACRE compilation [Angulo et al., Nucl. Phys. A 656 (1999) 3] is presented. This new compilation, referred to as NACRE II, reports thermonuclear reaction rates for…

Symmetry energy: nuclear masses and neutron stars

J. M. Pearson, N. Chamel, A. F. Fantina +1

We describe the main features of our most recent Hartree-Fock-Bogoliubov nuclear mass models, based on 16-parameter generalized Skyrme forces. They have been fitted to the data of…

The ratio method: a new tool to study one-neutron halo nuclei

P. Capel, R. C. Johnson, F. M. Nunes

Recently a new observable to study halo nuclei was introduced, based on the ratio between breakup and elastic angular cross sections. This new observable is shown by the analysis o…

Barrier penetration effects in the triple-alpha reaction at low energies

Y. Suzuki, P. Descouvemont

We investigate the triple-alpha reaction at low energies, by assuming a direct process. The Coulomb potential of three particles is examined carefully. The three-body continuum…

Bohr Hamiltonian with deformation-dependent mass term for the Kratzer potential

Dennis Bonatsos, P. E. Georgoudis, N. Minkov +2

The Deformation Dependent Mass (DDM) Kratzer model is constructed by considering the Kratzer potential in a Bohr Hamiltonian, in which the mass is allowed to depend on the nuclear…

Toward a microscopic description of reactions involving exotic nuclei

P. Descouvemont, M. S. Hussein

We propose an extension of the Continuum Discretized Coupled Channels (CDCC) method, where the projectile is described by a microscopic cluster model. This microscopic generalizati…

Skyrme effective pseudopotential up to next-to-next-to leading order

D. Davesne, A. Pastore, J. Navarro

The explicit form of the next-to-next-to-leading order (N2LO) of the Skyrme effective pseudopotential compatible with all required symmetries and especially with gauge invariance i…

Does a proton "bubble" structure exist in the low-lying states of 34Si?

J. M. Yao, H. Mei, Z. P. Li

The possible existence of a "bubble" structure in the proton density of Si has recently attracted a lot of research interest. To examine the existence of the "bubble" struct…

Sum rule approach to a soft dipole mode in hypernuclei

F. Minato, K. Hagino

Applying the sum rule approach, we investigate the energy of a soft dipole motion in hypernuclei, which results from a dipole oscillation of a hyperon against the core nucl…

Precise determination of the effective-range parameters up to an arbitrary order

O. L. Ramírez Suárez, J-M. Sparenberg

We propose a method to compute, for a given potential model, an arbitrary coefficient of the effective-range function expanded as a power series in energy. The method is based on a…

Beyond relativistic mean-field studies of low-lying states in neutron-deficient krypton isotopes

Y. Fu, H. Mei, J. Xiang +3

Neutron-deficient krypton isotopes are of particular interest due to the coexistence of oblate and prolate shapes in low-lying states and the transition of ground-state from one do…

Quasielastic and multinucleon excitations in antineutrino-nucleus interactions

M. Martini, M. Ericson

We investigate the MiniBooNE recent data on the antineutrino nucleus interaction, using the same theoretical description with the same parameters as in previous works on neutrino i…

Unified ab initio approach to bound and unbound states: no-core shell model with continuum and its application to 7He

Simone Baroni, Petr Navratil, Sofia Quaglioni

We introduce a unified approach to nuclear bound and continuum states based on the coupling of the no-core shell model (NCSM), a bound-state technique, with the no-core shell model…
