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...

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...

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...

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...

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...
