Energy and A-dependences of pion yields from nuclei at initial energies from 1.0 to 9.0 GeV/c

The dependences of charged pion yields from nuclei on the momentum and type of the bombarding particle and atomic weight of the nucleus-target are measured and analyzed. The measurements are performed at 59, 89, 119 and 160 deg angles in pA (A=Be, C, Al, Ti, Fe, Cu, Nb, Cd, Sn, Ta, Pb, U) and πsup(+-)A (A=C, Cu, Pb, U) - interactions at bombarding particles momenta of 1-9 GeV/s and 1.0-6.0 GeV/s, respectively. The obtained differential cross section values of pion production are tabulated. Given are graphical dependences of pion yields from different nuclei on the bombarding hadron momentum for various exit angles. For all angles the pion yield value is changed with the initial momentum growth differently for various bombarding particles, the change in the yield value is decreased with the initial momentum growth. That more the nucleus-target atomic weight than the stronier the dependence of pion yields on the bombarding particle momentum. The of differential cross section of pions production in pA - interactions at 7.5 GeV/s is described rather well by the Asup(α) form dependence (particularly for 119 and 160 deg angles); α=1. The α values increases with the initial momentum growth up to approximately 5-6 GeV/o then it goes out on the constant value. Such a behaviour is identical for various bombarding particles
