Abstract

Elastic scattering and breakup reactions represent efficient tools to investigate the structure of exotic nuclei. The main issue for theory is to determine their spectroscopic properties from the measured cross sections. The Continuum Discretized Coupled Channel (CDCC) method (at energies around the Coulomb barrier) and the eikonal method (at high energies) are widely used in reaction theories. Both approaches rely on projectile wave functions as accurate as possible.
In this talk I present recent applications of the CDCC and eikonal methods with various types of projectile wave functions. Two-body (such as 11Be=10Be+n) and three-body (such as 11Li=9Li+n+n) examples are shown. In particular, recent data on the 11Be+64Zn elastic scattering are analysed in the CDCC formalism, and the inelastic process is discussed. I also present recent results, obtained with the eikonal method, on the 11Li breakup at high energies.
