In this presentation, I will expose some of the last developmentsin microscopic nuclear structure calculations for exotic nuclei far from stabilitity [1].
In a first part, I will expose recent study on the development of collectivity in neutron-rich nuclei around N=40, where recent experimental evidence suggest a rapid change from the spherical to rotational regime, in analogy to the island...
.High resolution laser spectroscopy gives access to properties of nuclear ground states and long-lived (> 5ms) isomeric states of radioactive nuclei far from stability, such as nuclear spins, nuclear magnetic and quadruple moments and charge radii [1]. These fundamental properties of exotic nuclei provide important information for the investigation of the nuclear structure in different regions...
.The QRPA approach, well known to be adapted for giant resonance description, is also a good formalism to describe low energy vibrational states for all multipolarities and parities with the same accuracy. We will present selected recent successful results obtained within the QRPA approach using the Gogny interaction.
First, we will compare the first 2+ collective state obtained in QRPA and...
.The concept of nuclear shape plays an important role in our present understanding of nuclear structure. For that reason it is important to have methods to infer the shape of a nucleus in any state of excitation or in particular in its ground state. In this talk I will describe how a proper measurement of the beta strength in beta decay studies can provide in particular cases information about...
.Coulomb excitation is one of the rare methods available to obtain information on static electromagnetic moments of short-lived excited nuclear states, including collective non-yrast levels. In the scattering of two nuclei, the electromagnetic field that acts between them causes their excitation. The process selectively populates low-lying collective states and is therefore ideally suited to...
