 This paper gives the knowledge about fragmentation of a fast moving loosely bound projectile (stable/radioactive) on to some light/heavy target is an important reaction channel. The fragments are produced either due to coulomb or nuclear or both interaction depending upon how close the projectile was to the target at the instant of dissociation. In case of light target and small impact parameter the break up occurs mainly through the nuclear interaction between the projectile and the target. The nucleosynthesis of the heavier elements in stellar environments have attracted much attention in nuclear astrophysics. The first two elements and their stable isotopes H and He emerged from high temperature and high density state of the expanding universe, the so called “Big-bang”. A small amount of Li was also produced in the Big–bang but the remainder of the Li isotopes and all of Be and B isotopes were produced by the interaction of cosmic radiation with the constituents of the inter stellar medium between stars .
