We present our investigations of the real and imaginary parts of third-order nonlinear susceptibility Γ°v Γ°3Γ Γ of C 60 thin films ($100 nm) by the Z-scan technique at the wavelength of Nd:YAG laser second harmonic radiation (532 nm, s ΒΌ 55 ps). Our studies have shown that the sign of Rev Γ°3Γ changed
