Abstract:
Experiments have been carried out to study the ‘heavy fragments’ emitted at wide angles in the interaction of 3.65 A GeV 16O ions with a thick Cu target, using a stack of CR-39 track detectors. Diametric distribution in a stack registering 16O-beam halo are compared with diameters observed in a stack placed downstream at an angle of 25°. There is a strong indication that the heavy fragments are scattered at large angles.
