Events collected by the Collider Detector at Fermilab (CDF) with
an energetic jet plus large missing transverse energy can be used to search
for physics beyond the Standard Model. We see no deviations from the
expected backgrounds and set upper limits on the production of new
processes. We consider in addition the production of light gravitinos
within the framework of the Gauge Mediated Supersymmetry Breaking models and
set a limit at 95% confidence level on the breaking scale sqrt F \geq 217
GeV, which excludes gravitino masses smaller than 1.1 x 10-5 eV/c2.
