  We have directly measured the ZZ-gamma and Z-gamma-gamma couplings by
studying p pbar --> l+ l- gamma + X, (l = e, mu) events at the CM energy of
1.8$ TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the
transverse energy spectrum of the photon in the signal events, based on the
data set corresponding to an integrated luminosity of 13.9 pb^-1 ($13.3 pb^-1)
for the electron (muon) channel, yields the following 95% confidence level
limits on the anomalous CP-conserving ZZ-gamma couplings: -1.9 < h^Z_30 < 1.8
(h^Z_40 = 0), and -0.5 < h^Z_40 < 0.5 (h^Z_30 = 0), for a form-factor scale
Lambda = 500 GeV. Limits for the Z-gamma-gamma$ couplings and CP-violating
couplings are also discussed.
