Second Look

This paper takes a second look at the methods used in deriving low energy theorems on pion photoproduction using the partially conserved axial vector current (PCAC) hypothesis. The discrepancy between a recent measurement of Eo+(γp→π0p) and theory is studied. Rescattering corrections to low energy theorems are made. A critique of some recent theory papers on this subject is presented.
