Abstract
Assuming the length of the 3[pi] cut to be finite and approximating the integrated 4[pi] amplitude by a constant, we derive an expression for the [pi][ital N[bar N]] form factor which is very close to that given by a simple pole. The specific predictions of the obtained form factor for the region of small momentum transfer are compared with existing effective pole formulas and discussed along the lines of the Goldberger-Treiman relation.
