8. Proposal for a Nuclear Charge Radius Measurement of the Halo Isotope 11Be

Dr Wilfried Nörtershäuser (University of Mainz)

A measurement of the optical isotope shift in beryllium isotopes will allow a model-independent determination of the nuclear charge radius of Be-7,9,10 and the halo nucleus Be-11. This is based on an accurate calculation of the mass-dependent part of the isotope shift in the respective transition, combined with a precise measurement of the total isotope shift. Both values must be...

36. The masses of neutron-rich zinc isotopes and their impact on nuclear astrophysics

Dr Alexander Herlert (European Organization for Nuclear Research (CERN))

Nucleosynthesis theory describes how elements and nuclides are formed in stellar evolution, e.g., violent processes like supernovae explosions. For the calculations of the various pathways from hydrogen to the heavier elements the nuclear properties of a large number of nuclides need to be known [1,2]. Especially in the case of the r-process, where elements heavier than iron are formed by...

29. WITCH: Studies made in 2005

Mr Sam Coeck (IKS, KULeuven)

06/02/2006, 16:40

During the last year, efforts were made to improve and understand in more detail the WITCH experimental setup. At the end of 2004 several problems were uncovered and a number of them have already been dealt with in detail. The MCP's used for tuning the ion beam in the setup where shown to have saturation effects but this problem is now understood and can be prevented. The behavior of...

48. The Ramsey method in high-precision Penning trap mass spectroscopy

Mr Sebastian George (GSI)

06/02/2006, 17:00

The mass is a fundamental property of a nuclide. Its measurement contributes to a variety of fundamental studies including tests of the Standard Model and the weak interaction. The limits of mass measurements of exotic nuclei have been extended considerably by improving and developing the Penning trap mass spectrometer ISOLTRAP at the ISOLDE facility at CERN. The mass resolving power...

52. Possible Physics interests for the trapping of radioactive Rb atoms

Dr Amine Cassimi (Ciril-Ganil)

06/02/2006, 17:20

At LPC Caen, a magnetic optical trap (MOT) has been developed for the trapping of Rb atoms. This device is a powerful tool for atomic physics studies when used in combination with the well-established Recoil Ion Mass Spectrometry method (MOTRIMS). At ISOLDE, this kind of trap could be used for the trapping of radioactive Rb, and possibly of radioactive K and Li atoms with a slightly...

17. Production and trapping of francium at LNL Legnaro

Dr Giulio Stancari (INFN Ferrara)

06/02/2006, 17:35

A facility for the study of francium atoms is operating at the INFN Laboratories in Legnaro (LNL). Data on production, transport and trapping is presented. Possible future developments at Legnaro and ISOLDE are discussed.
