41. Perspectives for 2n transfer reactions at REX-ISOLDE

Prof. Reiner Krücken (Physik Department E12 - Technische Universität München)

Two-neutron transfer reactions offer the possibility to study pairing correlations, shape coexistence and other strcutural issues in nuclei. Our recent development of a tritium target opens the possibility to perform (t,p) reactions in inverse kinematics at REX-ISOLDE with beam intensities as low as approx. 10^5 pps. In this talk I will report on results of recent transfer experiments in...

13. Measuring the strength of the proton d5/2 - neutron d3/2 tensor-monopole interaction

The replacement of the N=20 spherical shell gap in nuclei of the island of inversion by the N=14,16 gaps can be explained by the tensor monopole interaction between the proton and neutron Fermi levels. The next step in understanding the evolution of shell structure is to measure the strengh of this interaction, which is present throughout the nuclear chart. The ideal tool for this are...

3. Results from Transfer Reactions at REX-ISOLDE and future plans

Vinzenz Bildstein (Physik-Department E12, TU München)

Transfer reactions yield important spectroscopic information about isotopes, including spin and parity assignments to nuclear levels and spectroscopic factors. The corresponding information is still lacking for many nuclei far from stability. The results from transfer experiments with neutron rich Na and Mg isotopes in inverse kinematic with the MINIBALL setup at REX-ISOLDE will be...

12. Transfer reactions with light radioactive ions at REX-ISOLDE

Henrik Jeppesen (European Organization for Nuclear Research (CERN))

In the second half of 2005 the Aarhus-Gothenburg-Madrid collaboration performed two different experiments impinging 11Be and 9Li on deuterium targets to study transfer reactions to different final states. This type of transfer reactions (at 2-3 Mev/u) gives information on several systems since both elastic scattering, stripping and pick-up channels are open. I would therefore like to...

50. Low energy Coulomb excitation of neutron-deficient 70Se at REX-ISOLDE

Mr Aaron Hurst (Liverpool University)

08/02/2006, 15:30

There is much ongoing experimental and theoretical interest surrounding nuclei in the $A=70$ region of the nuclear chart. A definitive measurement of the reorientation matrix element of the first 2+ state in 70Se would provide information on the nature of shape coexistence in this nucleus. Preliminary results following the Coulomb excitation of a radioactive beam of 70Se at 2.94 MeV/u...
