{pi}{sup 0} photoproduction on the neutron near threshold

Technical Report:

Abstract

Neutral pion photoproduction on the neutron near threshold is investigated with the dynamical model of Nozawa, Blankleider and Lee. It is shown that the final state interaction (FSI) amplitude derived from the dynamical model, could involve large cancellations between the different pion photoproduction mechanisms. We find that the FSI plays an essential role in this channel because of the small Born amplitude. At threshold, we obtain E{sub 0+}({pi}{sup 0}n) = 0.21 x 10{sup -3}/m{sub {pi}+}.
