Shape coexistence in nuclei appears to be unique in the realm of finite many-body quantum
systems. It differs from the various geometrical arrangements that sometimes occur in a …

The atomic nucleus is a quantum many-body system whose constituent nucleons (protons
and neutrons) are subject to complex nucleon-nucleon interactions that include spin-and …

We derive new Hamiltonians for the sd shell, USDA and USDB, based on a renormalized G
matrix with linear combinations of two-body matrix elements adjusted to fit a complete set of …

We report the measurement of reaction cross sections (σ R ex) of F 27, 29 with a carbon
target at RIKEN. The unexpectedly large σ R ex and derived matter radius identify F 29 as …

The tensor force is implemented into the mean-field model so that the evolution of nuclear
shells can be described for exotic nuclei as well as stable ones. Besides the tensor-force …

Recently, the idea of quantum phase transitions has been applied to equilibrium shape
changes in finite atomic nuclei. An introduction to and discussion of this concept, both from …

Interaction cross sections (σI) for Ne isotopes from the stability line to the vicinity of the
neutron drip line have been measured at around 240 MeV/nucleon using BigRIPS at RIBF …

This overview discusses the evolution of collectivity in atomic nuclei, with particular focus on
the rapidly develo** field of quantum phase transitions in the nuclear shape, and on …

The breakdown of the N= 20 magic number in the so-called island of inversion around Mg
32 is well established. Recently developed large-scale shell-model calculations suggest a …

Background: The density profile of exotic nuclei can be a rich source of information on the
nuclear surface. In particular, the nuclear surface diffuseness is correlated with the …
