The ground-state mass excess of the Tz=− 2 drip-line nucleus 22Al is measured for the first
time to be 18103 (10) keV using the newly-developed Bρ-defined isochronous mass …

In this paper we study the mass relation of mirror nuclei with our focus on pairing and shell
effects in the Coulomb energy. We present an accurate mass formula for neutron-deficient …

The recently observed abnormal bifurcation of the double binding energy differences δ V pn
between the odd-odd and even-even nuclei along the N= Z line from Ni to Rb has …

Applications of the proxy-SU (3) model of Bonatsos and collaborators to nuclei in A= 60–90
region introduces proxy-SU (4) symmetry. Shell model spaces with single particle orbits 1 p …

The model uncertainties in predictions of nucleon separation energies are investigated
based on four nuclear mass models and the measured masses of mirror nuclei. It is found …

Nuclear mass measurements have recently been extended conspicuously to proton-rich
region in the upper fp shell. The new data are utilized to study isospin symmetry breaking …

Mirror energy difference is a key observable in isospin symmetry breaking, containing rich
information about nuclear structure. Understanding the mechanisms underlying mirror …

A dedicated isochronous storage ring, named the Rare-RI Ring, was constructed at the RI
Beam Factory of RIKEN, aiming at precision mass measurements of nuclei located in …

Machine learning methods have recently gained interest in the complexity of nuclear mass
prediction. According to previous studies, we propose a continuous Bayesian probability …

The mass of neutron-deficient nuclide Zn 58 has been directly measured by using B ρ-
defined isochronous mass spectrometry, resulting in a more precise proton separation …
