【 摘 要 】

An optical model analysis of6He+9Be elastic scattering angular distributions at two energies above the Coulomb barrier is presented. A cluster model is used for the projectile- target optical potential which is decomposed into two components, the alpha-target and the 2n-target interactions. The 2n-target is adjusted to fit the data and a long range imaginary part is obtained.
