Some years ago, unnatural-parity doublet states in 212Po with spins of 4-, 6-, and 8-, which were observed to decay via strong E1 transitions to the yrast band in an experiment performed with the EUROBALL spectrometer, were interpreted as being of alpha-cluster structure. Subsequent theoretical work seemed to support this interpretation. The aim of experiment E693 was to study the...

Nuclei around N=60, Z=40 show a rapid variation in the deformation of their ground state with a rather small change in the neutron number. This feature manifests a subtle interplay between different aspects of the forces in the nucleus and makes this region an ideal testing ground for various nuclear structure theories. As an example, it is established that the ground state of Zr isotopes vary...

The goal of Experiment E706 was to measure lifetimes of excited states in neutron-rich fission fragments in the mass A≈110 region. A beam of 238U was incident on a 9Be target, which was mounted in the OUPS plunger device together with a Mg degrader foil. The fission fragments were identified in mass and atomic number in the VAMOS++ spectrometer, while γ rays were detected with the AGATA and...

Light neutron-rich nuclei, such as C and N isotopes, are a fertile ground for nuclear structure and nuclear astrophysics studies. Several nuclei in this region were populated in an experiment realised in GANIL, employing the deep-inelastic reaction $^{18}$O (7.0 MeV/A) + $^{181}$Ta and studied exploiting the state-of-the-art AGATA gamma-tracking array, coupled to the PARIS scintillation array...

This was the first experiment with NEDA and the full setup, and it suffered of some issues.

The (alpha+n) channel 63Ge has been searched carefully, so far without success. Many contaminating channels contribute to the background. In particular, we have found contaminant channels from the reaction induced by 40Ar, present in the beam producing residues with larger cross sections for...
