Abstract: The yields of cumulative protons and $\pi^{\pm}$ mesons emitted at a laboratory angle of 40$^\circ$ from carbon and heavier nuclear targets irradiated by a proton beam from the U70 accelerator (Institute for High Energy Physics, Protvino) have been studied in the SPIN experiment. It has been found that the effect of the target nucleus on the yield of particles with large transverse momenta is weakened.
