Threshold pi exp 0 -Meson Photoproduction on the Lightest Nuclei

摘要

The method of evolution with respect to coupling constant is applied to the pi exp 0 -meson photoproduction on the lightest nuclei d, exp 3 He, exp 3 H, exp 6 Li near threshold. The amplitude sensitivity of the process to the elementary pi N-data is studied. A quantitative analysis of contributions of the double counting rescattering effect of pions is given. Calculated amplitudes are in good agreement with experimental ones. (Atomindex citation 13:663559)
