The emission angle and the transverse momentum distributions of projectile fragments(PFs) produced in fragmentation of silicon on carbon and polyethylene targets at a few hundred MeV/nucleon are measured. It is found that the average emission angle and transverse momentum increase with the decrease of the charge of PFs for the same taget, and no obvious dependence of angular and transvers distribution on the mass of target nucleus is found for the same PF. The comulated squared transverse momentum distribution of PF can be well explained by a single Rayleigh distribution. The temperature parameter of PF emission source do not depend on the size of PF and mass of target with charge5<Z<14.
