The first search at a hadron collider for the production of
excited and exotic electrons in association with a positron is presented.
The excited electron decays to an electron and a photon with high transverse
momentum yielding an electron + positron + photon final state signature.
The search uses 202 pb-1 of data collected in p anti-p collisions at s**(1/2) =
1.96 TeV with the CDF II detector during 2001-2003. No excess of dielectron
+ photon events is observed. We present the e* sensitivity in the
parameter space of the excited electron mass and the compositeness energy
scale for both a gauge mediated and contact interaction model.
