In the cloudy-bag model, the value of the electric dipole amplitude of the photoproduction of neutral pions off protons at threshold connected with the additional contribution from the chiral symmetry breaking interaction is evaluated. If this additional contribution is included in the amplitude of the photoproduction of neutral pions off protons at threshold, the discrepancy between the LET predictions and the measured value of the electric dipole amplitude [Formula: see text] can be resolved for the values of quark masses and bag radii which are close to the generally used values.

Pion Capture

Differential and total cross sections are calculated for charged pion photoproduction and radiative pion capture in flight close to threshold [Formula: see text], mainly for a target of 12C. At the lower energies, selective bound state excitation may be studied in photo-production since the giant resonance is kinematically suppressed here. Pion absorption is found to increase considerably with decreasing pion energy due to a 1/νπ factor, and it shows a dip in the forward direction except for the 1+ state. Distortion and absorption effects on the pion are calculated, and are estimated to lead to only a small reduction of the cross section in the energy region considered.
