High-Statistics Sub-Barrier Coulomb Excitation of Sn
International audienceA Coulomb excitation campaign on Sn at 4.4â4.5â
MeV/u was launched at the HIE-ISOLDE facility at CERN. Larger excitation cross sections and Îł-ray statistics were achieved compared to previous experiments at âŒ2.8â
MeV/u. More precise values, lifetimes of states via the Doppler shift attenuation method, and new and values from the new Miniball data will be obtained and applied to test modern nuclear structure theories
decay studies of n-rich Cs isotopes with the ISOLDE Decay Station
Neutron-rich Ba isotopes are expected to exhibit octupolar correlations, reaching their maximum in isotopes around mass AÂ =Â 146. The odd-A neutron-rich members of this isotopic chain show typical patterns related to non-axially symmetric shapes, which are however less marked compared to even-A ones, pointing to a major contribution from vibrations. In the present paper we present results from a recent study focused on ÎČ-decay performed at the ISOLDE Decay Station equipped with fast-timing detectors. A detailed analysis of the measured decay half-lives and decay scheme of is presented, giving a first insight in the structure of this neutron-rich nucleus
