Résumé
Nous rapportons l'observation d'un nouveau phénomène de polarisation des fragments du projectile dans les collisions d'ions lourds de haute énergie. Le comportement de cette polarisation (qui vaut jusqu'à 20% au maximum et dépend de l'impulsion du fragment) s'interprète à partir d'un simple argument cinématique. Nous discutons aussi de la perspective de produire des faisceaux radioactifs (RI) pour des applications.
Abstract
A new polarization phenomenon observed for projectile fragments in high-energy heavy ion collisions is reported. Polarization was as large as about 20% at maximum and exhibited a systematic dependence on the momentum of the fragment. The behavior of the polarization is interpreted in terms of a simple kinematical argument. The prospect of producing polarized RI beam for practical applications is also discussed.
