Abstract
The emission angle and the transverse momentum distributions of projectile fragments (PFs) produced in fragmentation of 28Si on C and CH2 targets at 775 A. MeV are measured. It is found that the mean emission angle and the mean transverse momentum increase with the decrease of the charge of PFs for the same target, and no obvious dependence of angular and transverse momentum distribution on the mass of target nucleus are found for the same PF. The cumulative squared transverse momentum distribution of PF can be well explained by a single Rayleigh distribution. The temperature of PF emission source do not depend on the size of PF and mass of target for PF with charge 5 ≤ Z < 13.
