摘要：

Cross sections, d2σdΩdT, on C12, Ca40,44,48 are presented for inclusive (π+,π-) and (π-,π+) reactions at an incident energy of Tπ=290 MeV with the exit pions detected over an energy range of Tπ=175-255 MeV at an angle of 60A°. These cross sections are found to vary systematically with reported proton-neutron differences in nuclear radial distributions. NUCLEAR REACTIONS C12, Ca40,44,48 (π±,πA); measured d2σdΩdT, T=290 MeV, θ=60A°, nondiscrete final states; discussed the sensitivity to proton-neutron differences. © 1979 The American Physical Society.
