Abstract

Velocity and angular distributions of projectile-like fragments were measured between $θ_{lab = 0}$ ° and 4° (inside the grazing angle) for the ${}^{40}$ Ar $+^{208}$ Pb system at 60 MeV/nucleon using a magnetic spectrometer. Velocity spectra are similar to those obtained at larger angles, while the angular distributions, very forward peaked for light nuclei, tend to become flat for the heaviest fragments. The influence of the Coulomb and nuclear deflection of the fragments is discussed.
