Abstract:
The invariant cross sections for π0 meson production in alpha—alpha and alpha—proton collisions at the ISR were meas- ured up to transverse momenta of and , respectively. These measurements are compared with π0 production in pp collisions at the same values of nucleon, and the variation of the nuclear A-dependence with pT is determined.
