We searched the diffractive heavy quark production in the
semi-electronic mode. Diffractive candidates are selected from
low Et electron sample in central region using the Roman pot
detector.
Observed diffractive electron candidate preshower pulse height distribution
consistent with a purely hadronic background origin.
We conclude that there is < 18.3 real diffractive electron events in
the sample (90% c.l., stat only).
An upper limit of heavy quark produced diffractively is 0.9%(90% c.l.)
in our pot acceptance (0<|t|<~1.5,~0.05
