  The emission angle and the transverse momentum distributions of projectile
fragments produced in fragmentation of $^{56}$Fe on CH$_{2}$, C, and Al targets
at 471 A MeV are measured. It is found that for the same target the average
value and width of angular distribution decrease with increase of the
projectile fragment charge, and for the same projectile fragment the average
value of the distribution increases and the width of the distribution decreases
with increasing the target charge number. The transverse momentum distribution
of projectile fragment can be explained by a single Gaussian distribution and
the averaged transverse momentum per nucleon decreases with the increase of the
charge of projectile fragment. The cumulated squared transverse momentum
distribution of projectile fragment can be well explained by a single Rayleigh
distribution. The temperature parameter of emission source of projectile
fragment, calculated from the cumulated squared transverse momentum
distribution, decreases with the increase of the size of projectile fragment.
