  A projectile (84^Kr_36) having kinetic energy around 1 A GeV was used to
expose NIKFI BR-2 emulsion target. A total of 700 inelastic events are used in
the present studies on projectile fragments. The emission angle of the
projectile fragments are strongly affected by charge of the other projectile
fragments emitted at same time with different emission angle is observed. The
angular distribution studies show symmetrical nature for lighter charge
projectile fragments. The symmetrical nature decreased with the charge of
projectile fragments. At ~4o of emission angle for double charge projectile
fragments, the momentum transfer during interaction is similar for various
target species of emulsion were observed. We also observed a small but
significant amplitude peaks on both side of the big peak for almost all light
charge projectile fragments having different delta angle values. It reflects
that there are few percent of projectile fragments that are coming from the
decay of heavy projectile fragments or any other process.
