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 …

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 N= 20 and N= 28 “islands of inversion” are described by large scale shell model
calculations with an extension of the interaction SDPF-U that makes it possible to mix …

The nuclear shell structure that has served as a fundamental framework for understanding
the arrangement of nucleons exhibits dramatic changes as the neutron to proton ratio in …

The formal theories of breakup reactions are reviewed. The direct breakup mechanism that
is formulated within the framework of the post-form distorted-wave Born approximation, is …

The experiments that provide information about the level structure of the “island of inversion”
isotopes 31 Mg and 33 Mg are reviewed. Since the model-independent measurement of …

Situated in the so-called “island of inversion,” the nucleus 32 Mg is considered as an
archetypal example of the disappearance of magicity at N= 20. We report on high statistics in …

We report on the first detailed study of intruder configurations in the ground state of 30 Ne by
means of the 12 C (30 Ne, 29 Ne+γ) X one-neutron knockout reaction at 228 MeV/nucleon …

The interaction cross sections of 32-35 Mg at 900 A MeV have been measurmed using the
fragment separator at GSI. The deviation from the r 0 A 1/3 trend is slightly larger for Mg 35 …

I will discuss the impact of the research on exotic nuclei carried out at ISOLDE and later on,
following its impulse, in many laboratories worldwide, in our present knowledge of the …
