摘要：

For the quasifree (pi-,pi0) reaction on a wide range of targets at 500 and 400 MeV, the measured effective numbers of protons are found to be in good agreement with those from a simple semiclassical attenuation model based on the nuclear density and the total cross section for free piN scattering. The A dependence for our experimental results was fitted by a power law (is-proportional-to A(alpha)), and the exponents ct were found to be 0.38 +/- 0.03 and 0.40 +/- 0.06 for 500 and 400 MeV (pi-,pi0), respectively.
