26. Coulomb excitation of 200Po studied at REX-ISOLDE with the Miniball γ spectrometer

Ms Nele Kesteloot (IKS KU Leuven, SCK Mol)

5/25/12, 11:30 AM

Heavy and superheavy nuclei

Oral

The neutron-deficient polonium isotopes with two protons outside the closed Z = 82 shell represent an interesting region of the nuclear chart to study shape coexistence in nuclei. 200Po manifests itself as a transitional nucleus between a general-seniority-type regime in the heaviest polonium isotopes and a shape-coexistence character in the lightest polonium isotopes [1,2]. However, questions...

95. Study of the 84Ga beta-decay at the ALTO facility

Ms Karolina Kolos (IPN Orsay, CNRS/Univ. Paris Sud)

Nuclear structure far from stability

Oral

There is an increasing interest in studying the evolution of the collectivity of neutron-rich nuclei beyond N=50. Germanium isotopes are well known to undergo collective effects such as vibrations or gamma softness. It is particularly interesting to study 84Ge as it is the first even-even nucleus beyond N=50. The nature of the collectivity can be probed by measuring the excitation energies of...

7. Hindered proton collectivity in the proton-rich nucleus 28S

Nuclear structure far from stability

Oral

The reduced transition probability B(E2) of the 0+ → 2+ transition in 28S was determined experimentally using the Coulomb excitation at 53 MeV/nucleon. The experiment was performed using the RI Beam Factory at RIKEN Nishina Center. The resultant B(E2) value is smaller than the expectation based on an empirical B(E2) systematics. The relative importance of the proton- and neutron-...

8. Transfer reaction studies of neutron rich Be isotopes.

Mr Jacob Johansen (Aarhus University)

5/25/12, 12:30 PM

Nuclear structure far from stability

Oral

On behalf of the MINIBALL and IS430 collaborations. A transfer reaction experiment was performed at ISOLDE in 2010 using a 11Be beam incident on both deuterons and protons. Both one neutron transfer and scattering reactions were detected enabling study of bound states and low lying resonances in 10Be, 11Be and 12Be. The MINIBALL Ge cluster along with the T-REX Si setup were used for...

25. Study of the weakly bound nucleus 26F

Mr Alexandre Lepailleur (GANIL)

5/25/12, 12:50 PM

Nuclear structure far from stability

Oral

Nuclear forces play a decisive role to account for the creation and modifications of shell gaps, to explain deformed nuclei, to permit the development of halo structures and to fix the limits of particle stability. The determination of nuclear forces inside the nucleus from bare forces is a tedious but important task. The neutron-rich 26F is a benchmark nucleus for studying proton-neutron...
