"Physics with spin-oriented exotic nuclear beams and
        examples of measurements of nuclear moments"
 
                     Dimiter Balabanski

 An overview of a series of recent experiments aimed at the
 determination of the moments of exotic nuclei produced in
 fragmentation reactions will be given. The spin-orientation:
 spin-alignment or spin-polarization of the nuclear ensemble,
 which is produced in a fragmentation reaction, is of utmost
 importance for these studies. The discussion will emphasize
 on the open problems related to the production and the
 preservation of the orientation during the experiments. Pros
 and contras for experiments at both, intermediate energies
 (~ 100 MeV/A) and high energies (~ 1 GeV/A) of the exotic
 beams will be considered.

 Examples will be provided from a series of nuclear moment
 measurements, which were performed using the LISE3
 spectrometer at GANIL. The spin-alignment and the
 spin-polarization of the nuclear ensemble were studied by
 the b-LMR and the b-NMR experimental techniques [1,2]. A
 devoted experiment was carried out to study systematically
 the orientation of Boron fragments as a function of the
 number of abraded nucleons in order to study the mechanism
 of creation of spin-orientation in fragmentation reactions.
 The experimental results will be discussed in the framework
 of the kinematical model of the fragmentation reaction
 [3,4].
