ABSTRACT

To understand various nuclear processes like generation of energy during evolutions of stars, supernova explosions, big-bang, solar neutrino problem etc., one need to know nuclear reaction cross sections at very low collision energies corresponding to the relevant astrophysical temperatures. Most of the astrophysical processes are related to some radiative capture reactions at low energies. Thus the knowledge of some specific radiative capture reaction cross-section is a key to explain these processes. Some astrophysical problems of current importance along with the associated radiative capture reactions are listed. 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. While, in a peripheral nuclear collision with impact parameter larger than the sum of the radii of colliding partners, the nuclear forces do not come into play and the projectile experiences, in the projectile frame of reference, a time varying electromagnetic field produced due to relative motion of the
