Abstract
Elastic scattering and inclusive breakup of 6Li particles on 12C, 58Ni,
90Zr, and 208Pb targets are measured at 100A MeV. The elastic scattering data are compared
with single channel and Coupled Discretized Continuum Channels calculations. The coupling-effect
between the elastic and the breakup channels is important even at an incident energy of 100A MeV and
cannot be neglected. The inclusive breakup data are investigated for orbital dispersion effects
which are found to be less significant at 100A MeV. The longitudinal momentum distributions are
broader than predicted by theoretical expectations.
