The beta-decay of 22Al

In an experiment performed at the LISE3 facility of GANIL, we studied the decay of 22Al produced by the fragmentation of a 36Ar primary beam. A beta-decay half-life of 91.1 +- 0.5 ms was measured. The beta-delayed one- and two-proton emission as well as beta-alpha and beta-delayed gamma decays were measured and allowed us to establish a partial decay scheme for this nucleus. New levels were determined in the daughter nucleus 22Mg. The comparison with model calculations strongly favours a spin-parity of 4+ for the ground state of 22Al

A new isomer in 125^{125}La

Levels in $^{125}$La have been studied via $\beta ^+$/EC decay of on-line mass-separated $^{125}$Ce using the HIGISOL technique. A new (390 $\pm$ 40) ms isomer is definitely attributed to $^{125}$La by conversion electron measurements of the 107 keV E3 isomeric transition

This paper propose a chart to assess the qualitative effetcts of cooperation among libraries. First, we have introduced the theoretical plat-form which guided us, on one hand, in accomplishing a field-study in the network of libraries associated with the french national library ; on the other hand, in setting up the assessement indicators of cooperation qualitative effects. This plat-form is made up of a network model as a three-dimensions relating machine (infrastructure, infostructure and infoculture) and of three levels of localising the qualitative network effects on a library, which are the library relationship with its external environment, its services offer and its internal environment. Second, we have relied on the field-study results to introduce a series of questions that the evaluator has to ask in order to obtain the indicators of qualitative effects. Finally, these indicators have been compared to referents (norms, standards, pre-define
