Multiplicities of π-mesons from central collisions ofC andO(4.5 GeV/c/n momentum) with several target nuclei were studied in a streamer chamber experiment. The parameter η=(〈n〉−〈n〉)/〈n〉 was determined for several samples of events characterized by different values of Θ - the 'vetoangle' for emission of the projectile charged fragments. The value of η is shown to decrease when the projectile mass number increases from 12 to 16 and to decrease significantly when Θ increases from 0° to 4°, whereas it remains nearly constant when Θ increases further to 14°. The results are compared with predictions of some theoretical models. [ABSTRACT FROM AUTHOR] |
