Abstract
A method is developed for separating nu N interactions from interactions in volving an intranuclear cascade in nu Ne scattering at a mean neutrino ener gy of 145 GeV. The fraction of events featuring a cascade is evaluated by u sing a sample of nu Ne charged-current interactions, It is found that the m ultiplicity of charged particles in the forward direction takes the same va lue for events with and without a cascade for 4 < W-2 < 550 GeV2. In the ba ckward direction, cascade events have the charge multiplicity higher than t he multiplicity for cascade-free events by 2.36 units. It is found that par ticles with momenta less than 2 GeV/c make a dominant contribution to the r escattering process. A depletion of the fastest particles for W-2 < 50 GeV2 is observed, in accord with the formation-time concept. (C) 2000 MAIK "Nau ka/Interperiodica".
