RATIOS OF THE CROSS-SECTIONS FOR THE PRODUCTION OF ISOSYMMETRIC CUMULATIVE PARTICLES AND THE MECHANISM OF DEEP-INELASTIC NUCLEAR-REACTIONS

The ratios of the observed yields of cumulative particles belonging to the same isospin multiplet are analyzed. The dependences of the isosp in ratios pi(-)/pi(+), n/p, and T/He-3 on the type of incident particl es, on thel isospin content of nuclei, and on the nuclear Coulomb fiel d are investigated. The contributions of these effects to the above is ospin ratios are shown to be on the same order of magnitude. An experi mental program is proposed that is aimed at measuring the isospin rati os to a precision of 2%, which is sufficient for separating contributi ons due to different processes and for drawing definite conclusions on the underlying mechanism of cumulative-particle formation.
