Levels of (6,3,4,5)- multiplet in 68,70Cu were populated by Coulomb excitation using 6- radioactive beams delivered by REX-ISOLDE. B(E2)/B(M1) reduced transition probabilties can be extracted and information about the single particle structure of the multiplet can be obtained.

2. Transient field g-factor measurements on radioactive nuclei following alpha transfer to energetic projectiles in inverse kinematics

Prof. Karl-Heinz Speidel (Helmholtz-Institut für Strahlen- und Kernphysik, Univ. Bonn)

In recent measurements of g factors and lifetimes of short-lived nuclear states several radioactive nuclei have been investigated which were produced in alpha-transfer reactions to stable projectiles at the Coulomb barrier employing the techniques of transient magnetic fields and Doppler-Shift-Attenuation, respectively. In particular, this method has been applied to 44Ti [1], 52Ti [2],...

4. Coulomb Excitation of Neutron-rich Xe-Isotopes at REX-ISOLDE

T. Behrens (Physics Department E12, TU München)

Recent studies on isotopes around the shell closure N=82 have shown that despite decreasing excitation energies the B(E2) values of Sn and Te isotopes above N=82 are lower than expected. The aim of our experiment was to measure B(E2) values in neutron-rich even-even isotopes around the double magic 132Sn. In a first campaign in 2004 we measured the gamma transitions of 122-126Cd. In 2005...

11. Results and experiences from Coulomb excitation experiments with radioactive beams at GANIL and ideas for future experiments at ISOLDE

Andreas Goergen (DAPNIA/SPhN, CEA Saclay)

08/02/2006, 10:05

Shape-coexisting states in neutron-deficient krypton isotopes have been studied by low-energy multi-step Coulomb excitation of radioactive 74Kr and 76Kr beams at GANIL. States up to the 8+ in the ground-state band and several non-yrast states have been populated, and their excitation probability was measured as a function of the scattering angle. A large set of both transitional and...

51. Nuclear Moments of Isomeric States at REX-ISOLDE - Ideas and Necessities

Dr Georgi Georgiev (IPNO)

08/02/2006, 10:25

The nuclear moments are an important ingredient of our nuclear structure knowledge. Their contribution is crucial when one discusses the development of the nuclear shells far from stability. However, presently there are no techniques that can be directly applied for the studies of short-lived isomeric states produced by ISOL beams. Some ideas about the use of post-accelerated radioactive...
