Abstract
We have perfomed studies of the direct emission ( ) and inner Bremsstrahlung ( ) vertices, based on data collected by KTeV during the 1996 Fermilab fixed target run. We find for the form-factor parameter in the -propagator parametrization, and report on fits of the form factor to linear and quadratic functions as well. We concurrently measure , and a branching ratio of .
