Nucleon-pair approximation with matrix representation
Y. Lei, Y. Lu, Y. M. Zhao
In this paper, we propose an approach of the nucleon-pair approximation (NPA), in which the collective nucleon pairs are represented in terms of antisymmetric matrices, and commuta…
Unitary limit and linear scaling of neutrons in harmonic trap with tuned CD-Bonn and square-well interactions
Yi-Yuan Cheng, Thomas T. S. Kuo, Ruprecht Machleidt +1
We study systems of finite-number neutrons in a harmonic trap at the unitary limit. Two very different types of neutron-neutron interactions are applied, namely, the meson-theoreti…
Mass dependence of symmetry energy coefficients in Skyrme force
N. Wang, M. Liu, H. Jiang +2
Based on the semi-classical extended Thomas-Fermi approach, we study the mass dependence of the symmetry energy coefficients of finite nuclei for 36 different Skyrme forces. The re…
New charge radius relations for atomic nuclei
B. H. Sun, Y. Lu, J. P. Peng +2
We show that the charge radii of neighboring atomic nuclei, independent of atomic number and charge, follow remarkably very simple relations, despite the fact that atomic nuclei ar…
Nucleon pair approximation description of the low-lying structure of Te and I
H. Jiang, Chong Qi, Y. Lei +3
The low-lying level schemes and electromagnetic transitions of Te, I, and the neighboring even-even nucleus Te, are calculated within the framework of the $…
Systematic study of proton-neutron pairing correlations in the nuclear shell model
Y. Lei, S. Pittel, N. Sandulescu +3
A shell-model study of proton-neutron pairing in shell nuclei using a parametrized hamiltonian that includes deformation and spin-orbit effects as well as isoscalar and isov…
