Sažetak
Complete angular distributions of the ^16O +^16O elastic channel have been measured at the 9 following bombariding energies: E_lab=0.75, 80.6, 87.2, 92.4, 94.8, 98.6, 103.1, 115.9 and 124 MeV using at forward angles (theta_lab=5^o to 20^o) the Q3D spectrometer and at backward angles (theta_lab=20^o to 50^o) two Position Sensitive Silicon detectors in kinematical coincidence. Refractive effects fiving rise to nuclear rainbows and the associated Airy structures have been observed for this system. An optical model analysis has been done where the real part of the potential has been determined with no ambiguity over the whole energy range whereas the absorption (imaginary part) changed drastically around E_lab=90 MeV.
