Nuclear shape coexistence is the phenomenon in which distinct shapes occur within the
same nucleus and at a similar energy. In this work, we provide an overview of the …

In this review, we describe the experimental facilities and methods which make it possible to
produce and measure the properties of the extreme neutron-rich nuclei. We then develop …

The shapes of neutron-rich exotic Ni isotopes are studied. Large-scale shell model
calculations are performed by the advanced Monte Carlo shell model (MCSM) for the pf-g …

Large-scale shell-model calculations predict that the region of deformation which comprises
the heaviest chromium and iron isotopes at and beyond N= 40 will merge with a new one at …

We first review the shell evolution in exotic nuclei driven by nuclear forces. We then
demonstrate that the underlying mechanism played by the balance of the tensor and central …

We present a review of several works using the finite-range Gogny interaction in mean field
approaches and beyond to explore the most striking nuclear structure features. Shell …

The internal-conversion and internal-pair-production decays of the first excited 0+ state in Ni
68 are studied following the β decay of Co 68. A novel experimental technique, in which the …

The interpretation of nuclear observables in the laboratory frame in terms of the intrinsic
deformation parameters β and γ is a classical theme in nuclear structure. Here we use the …

Intermediate-energy Coulomb excitation measurements were performed on the neutron-rich
isotopes 58, 60, 62 Cr. The electric quadrupole excitation strengths, B (E 2; 0 1+→ 2 1+), of …

Shape coexistence in neutron-rich nuclei in the N= 20 island of inversion, along the N= 28
isotone line, and in the region around neutron number N= 40 is reviewed. The present …
