A-dependence of πsup(+-) meson photoproduction cross-section at 3.0 GeV
Description
Experimental data are presented on the inclusive photoproduction of πsub(+-) mesons with the energy of Esub(π) (>approximately) 45 MeV in the angle range of 45 deg-150 deg at the energy of bremsstrahlung photons (Esub(γ))sub(max)=2.5 and 3.5 GeV on C12, Al27, Cu63, Sn118, Pb208 nuclei. By the substraction method obtained are angular dependences of the differential cross section of the πsup(+-) meson photoproduction on nuclei and A dependence of the integrated cross section at the fixed energy of initial photons Esub(γ)=3.+ 0.5 GeV. It is shown that in these kinematic conditions in Asup(n) dependence of the πsub(+-) meson photoproduction cross section the exponent n=0.849+-0.023
