Abstract
The dependence of breakup cross sections of 8B at 65MeV/nucleon on the target mass number A T is investigated by means of the continuum-discretized coupled-channels method (CDCC) with more reliable distorting potentials than those in the preceding study. The A 1/3 T scaling law of the nuclear breakup cross section is found to be satisfied only in the middle A T region of 40 A T 150. The interference between nuclear and Coulomb breakup amplitudes vanishes in very forward angle scattering, independently of the target nucleus. The truncation of the relative energy between the p and 7Be fragments slightly reduces the contribution of nuclear breakup at very forward angles, while the angular region in which the first-order perturbation theory works well does not change essentially.
