Effective pairing interactions with isospin density dependence
J. Margueron, H. Sagawa, K. Hagino
We perform Hartree-Fock-Bogoliubov (HFB) calculations for semi-magic Calcium, Nickel, Tin and Lead isotopes and =20, 28, 50 and 82 isotones using density-dependent pairing inter…
BCS-BEC crossover of neutron pairs in symmetric and asymmetric nuclear matter
J. Margueron, Hiroyuki Sagawa, Kouichi Hagino
We propose new types of density dependent contact pairing interaction which reproduce the pairing gaps in symmetric and neutron matter obtained by a microscopic treatment based on…
Pairing Correlations in halo Nuclei
H. Sagawa, K. Hagino
Paring correlations in weakly bound halo nuclei He and Li are studied by using a three-body model with a density-dependent contact interaction. We investigate the spat…
Dipole excitation and geometry of borromean nuclei
K. Hagino, H. Sagawa
We analyze the Coulomb breakup cross sections of Li and He nuclei using a three-body model with a density-dependent contact interaction. We show that the concentration o…
Charge radius and dipole response of Li
H. Esbensen, K. Hagino, P. Mueller +1
We investigate the consistency of the measured charge radius and dipole response of Li within a three-body model. We show how these observables are related to the mean squar…
Shell Structure and -Tensor Correlations in Density-Dependent Relativistic Hartree-Fock theory
Wen Hui Long, Hiroyuki Sagawa, Nguyen Van Giai +1
A new effective interaction PKA1 with -tensor couplings for the density-dependent relativistic Hartree-Fock (DDRHF) theory is presented. It is obtained by fitting selected empir…
