Résumé :

Calculations of the breakup of B8 and Be11 are performed with the aim of analyzing their sensitivity to the projectile description. Several potentials adjusted on the same experimental data are used for each projectile. The results vary significantly with the potential choice, and this sensitivity differs from one projectile to the other. In the B8 case, the breakup cross section is approximately scaled by the asymptotic normalization coefficient (ANC) of the initial bound state. For Be11, the overall normalization of the breakup cross section is no longer solely determined by the ANC. The partial waves describing the continuum are found to play a significant role in this variation, as the sensitivity of the phase shifts to the projectile description changes with the physical constraints imposed to the potential. © 2006 The American Physical Society.
