  The MSSM with explicit CP violation is studied through the di-photon decay
channel of the lightest neutral Higgs boson. Through the leading one-loop order
H1 --> gammar.gamma is affected by a large number of Higgs-sparticle couplings,
which could be complex. Our preliminary scan over the Supersymmetric parameter
space shows that more than 50% average deviations are possible, in either
direction, in the corresponding branching ratio, with respect to the case of
the CP-conserving MSSM. In particular, our analysis shows that in the presence
of a light stop (with mass ~ 200 GeV) a CP-violating phase Arg(mu) ~ 90(deg)
can render the H1 --> gamma.gamma branching ratio more than 10 times larger,
for suitable combinations of the other MSSM parameters.
