On the distribution of spectator fragments in processes involving relativistic nuclei

Distributions of spectator fragments are studied in the knockout processes involving relativistic nuclei. Considerations are based on the 'light front' form of the quasipotential dynamics. The distribution of spectators is expressed by means of the overlap integral of the relativistic wave functions of an incident nucleus and a fragment one. This distribution allows the picture of the longitudinal and transversal motion of nucleons in the incident nucleus to be reproduced. The results obtained can be used for the analysis of data obtained in experiments with beams of relativistic nuclei
