We present a search for excited and exotic electrons (e*)
decaying to an electron and a photon, both with high transverse momentum.
We use 202 pb-1 of data collected in p anti-p collisions at s**(1/2) = 1.96 TeV
with the CDF II detector. No signal above standard model expectations is
seen for associated ee* production. We discuss the e* sensitivity in the
parameter space of the excited electron mass M_e* and the compositeness
energy scale Lambda. In the contact interaction model, we exclude 132 <
M_e* < 879 GeV/c2 for Lambda = M_e* at 95% confidence level (C.L.). In
the gauge-mediated model, we exclude 126 < M_e* < 430 GeV/c2 at 95% C.L.
for the phenomenological coupling f/Lambda approx 10-2 GeV-1.
