Abstract
A thorough theoretical analysis of fast and slow hadrons emitted in the forward (theta<90 degrees) and backward (theta greater than or equal to 90 degrees) hemispheres in the interactions of Li-6 (3.7A GeV) with emulsion nuclei is made with a modified FRITIOF model (which allowance is made for secondary interactions) and a typical cascade model. It is found that, while the cascade model applies well in the region of limited cascading (backward hemispheres), it becomes less applicable in the forward hemisphere (where cascading becomes more branched). The modified FRITIOF model, on the other hand, could reproduce the experimental observations in both hemispheres. [S0556-2813(99)00205-8].
