Continuum spectrum in the quasifree ( p,2p) scattering

It is assumed that the rescattering of the quasifree particles on the spectator part of the target nucleus constitutes the major source of the pre-equilibrium events situated beyond the four-body kinematic limit in the reaction phase space. A preliminary analysis suggests that the pre-equilibrium spectrum can be calculated in terms of the inelastic scattering of the quasifree particles on the spectator nucleus. Comparison with the /sup 58/Ni( p,2p)/sup 57/Co data at E/sub 0/ = 198 MeV supports the model prediction.
