The competition between spherical and deformed configurations at low energy gives rise to shape coexistence in the neutron-deficient isotopes around Z~82 and N~104 [1]. Along the isotope chain of a number of elements this leads to an abrupt change in the mean-square charge radius of the nuclear ground state when entering the neutron-deficient region. The most notorious case is the shape...

A kink at a nucleon shell closure in mean-square charge radii r2 along an isotopic chain is a distinct feature of charge radii [1], though the underlying mechanism still remains elusive. Such a feature is clearly visible in the Ca chain at the N = 28 neutron shell closure, which has been a major challenge for nuclear theory to understand [2]. In the present study, the r2 of 52,53Fe below N =...

Electron elastic scattering is a simple but very powerful tool to investigate the detailed internal structures of nuclei since it can measure the precise charge density distribution through the well-known electromagnetic interaction. Although the charge density distributions have been already measured for many stable nuclei by former electron scattering experiments, the method has yet to been...

Due to the two-body nature of the alpha decay, nuclear alpha spectroscopy has become one of the most relied upon techniques for accurate linking of nuclear masses. Based on a single nucleus of well-known mass serving as anchor point, masses of all mother and daughter nuclei that possess an alpha-decay channel can be determined precisely by the energy of the emitted alpha particles and, if...

Precision mass measurements of unstable nuclei, providing direct measure of the nuclear binding energy, are invaluable for nuclear structure study and have potential for particle identification of atomic nuclide by the precision mass value. For trans-fermium nuclei, of importance for understanding the shell evolution in heavy nuclear system to inspect mass models toward so-called island of...

More than 50 super-heavy nuclei, which have been identified in fusion-evaporation reactions between 48Ca beams and actinide targets [1,2], form what is known as the ‘Hot Fusion Island’ - a part of the Island of Stability. Most of these nuclei have been discovered in experiments at the Dubna Gas Filled Recoil Separator (DGFRS), using actinide target materials produced at Oak Ridge National...

The neutron-deficient 240Es nucleus was synthesized for the first time using the fusion-evaporation reaction 209Bi(34S,3n)240Es at the Accelerator Laboratory of University of Jyväskylä (JYFL), Finland. The gas-filled recoil separator RITU [1] was used to separate the fusion-evaporation products from the primary and scattered beam. The radioactive decays originating from 240Es and its...
