Effective proton-neutron interaction in mirror nuclei
Y. M. Xing, Y. F. Luo, K. H. Li +9
Effective proton-neutron interactions, , in mirror nuclei are systematically analyzed using the ground-state atomic masses. A mirror symmetry of is found for bound…
Exploring isospin-nonconserving effects in the upper shell with new mass measurements
H. F. Li, X. Xu, Y. Sun +8
Nuclear mass measurements have recently been extended conspicuously to proton-rich region in the upper shell. The new data are utilized to study isospin symmetry breaking phen…
Investigation of isospin-symmetry-breaking in mirror energy difference and nuclear mass with ab initio calculations
H. H. Li, Q. Yuan, J. G. Li +7
Isospin-symmetry breaking is responsible for the energy difference of excited states in mirror nuclei. It also influences the coefficient of the isobaric multiplet mass equation. I…
Ab initio descriptions of mirror nuclei with resonance and continuum coupling
S. Zhang, F. R. Xu, J. G. Li +6
We have used an {\it ab initio} Gamow shell model to study the isospin symmetry breaking in the mirror nuclei of F, N, Ne and C. Starting from a…
Systematic trends of neutron skin thickness versus relative neutron excess
J. T. Zhang, X. L. Tu, P. Sarriguren +7
Available experimental neutron skin thicknesses of even-even stable Ca, Ni, Sn, Pb, and Cd isotopes are evaluated, and separate trends of neutron skin thickness versus relative neu…
Probing the nature of the conjectured low-spin wobbling bands in atomic nuclei
S. Guo, X. H. Zhou, C. M. Petrache +28
Precession is a unique motion in which the orientation of the rotational axis of a rotating body is not fixed but moving, and it generally exists in the Universe from giant stars t…
Valence Neutron-Proton Orientation in Atomic Nuclei
J. G. Wang, M. L. Liu, C. M. Petrache +3
It is shown that the renormalized nuclear deformations in different mass regions can be globally scaled by two probability partition factors of Boltzmann-like distribution, which a…
Generalized isobaric multiplet mass equation and its application to the Nolen-Schiffer anomaly
J. M. Dong, Y. H. Zhang, W. Zuo +3
The Wigner Isobaric Multiplet Mass Equation (IMME) is the most fundamental prediction in nuclear physics with the concept of isospin. However, it was deduced based on the Wigner-Ec…
Isomerism in the "south-east" of Sn and a predicted neutron-decaying isomer in Pd
Cenxi Yuan, Zhong Liu, Furong Xu +11
Excited states in neutron-rich nuclei located south-east of Sn are investigated by shell-model calculations. A new shell-model Hamiltonian is constructed for the present st…
Beyond Wigner's isobaric multiplet mass equation: Effect of charge-symmetry-breaking interaction and Coulomb polarization
J. M. Dong, J. Z. Gu, Y. H. Zhang +4
The quadratic form of the isobaric multiplet mass equation (IMME), which was originally suggested by Wigner and has been generally regarded as valid, is seriously questioned by rec…
Green's function method for single-particle resonant states in relativistic mean field theory
T. T. Sun, S. Q. Zhang, Y. Zhang +2
Relativistic mean field theory is formulated with the Green's function method in coordinate space to investigate the single-particle bound states and resonant states on the same fo…
