Abstract Multiplicities of π−-mesons from central collisions of12C and16O(4.5 GeV/c/n momentum) with several target nuclei were studied in a streamer chamber experiment. The parameter η=(〈n − 2 〉−〈n−〉2)/〈n−〉 was determined for several samples of events characterized by different values of Θ ch — 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 ch increases from 0° to 4°, whereas it remains nearly constant when Θ ch increases further to 14°. The results are compared with predictions of some theoretical models.
