Influence of the projectile description on breakup calculations

Abstract

Calculations of the breakup of 8B and 11Be 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 8B case, the breakup cross section is approximately scaled by the asymptotic normalization coefficient of the initial bound state (ANC). For ${}^{11}$Be, 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.
