The experimental data of nucleon-nucleus collisions of energies around 100 GeV have been analysed. It is pointed out that the transverse momentum, pr, of shower particles is also an adequate parameter to analyse the nucleon-nucleus collision. The transverse momenta, both in the average value and in the distribution, are similar to the case of the nucleon-nucleon collision. Both the median angle and the average number of shower particles increase with the number of heavily ionizing prongs, N/_n. The latter observations exclude the possibility that, for primary energy at least up to several tens GeV, the target of events with high N_n is effectively a single nucleon. Although conclusive evidence to rejcct the model of cascade development (of nucleon-nucleon and pion-nucleon collisions) is not presented, this model seems to be disagreement with the data of _<PT>.
