“…By using the A 1/3 scaling of nuclear radii, the CDE for the T = 1/2 mirror nuclei can be expressed as 6e 2 Z < /5A 1/3 [32]. Apart from the shell, deformation and pairing effects, CDE can be fitted by an empirical linear formula with two parameters B 1 and B 2 [33,34]:…”

“…It is well known that the deformation can lead to modifications of single-particle states and cause qualitative changes in the structure, and therefore could alter the linear dependence of CDE on Z < /A 1/3 . If one assumes that a deformed nucleus has a quadrupole deformation β, then the modified CDE, E c (β ), can be estimated by the following expression [34]:…”

The recent advances in nuclear mass measurement have sparked discussions on the isospin-symmetry breaking reflected in the Coulomb displacement energy (CDE). The current data suggested that the regular phase of the odd-even staggering in CDE for the T = 1/2 mirror nuclei persists up to A = 67 and changes at A = 69. Shell-model calculations using the modern GXPF1A and JUN45 effective interactions with a proper treatment of the Coulomb and isospin-nonconserving forces cannot describe the observation. Inspired by recent work (Kaneko 2013 Phys. Rev. Lett. 110 172505), we investigate the systematic behavior of CDE along the N = Z line up to the heaviest available masses. Starting from A ≈ 65, a systematic deviation is observed between the experimental data and the model estimations assuming the nucleus as a homogeneously charged sphere. Possibilities that may resolve the conflict between the experimental mass and theoretical expectations for the 69 Br-region are discussed, and new mass experiments are called for.
