Scatter Plot from Scientific Research

Frequency dependence of the photo-susceptibility of K 3 C 60 defined as the gradient of the lost spectral weight in (\({\sigma }_{1}\)) in the low-fluence limit (Supplementary Section 8 ) measured 10 and 50 ps after photo-excitation. These measurements were carried out at a base temperature T = 100 K. These data were obtained by accounting for the inhomogeneous excitation of the probed volume under the assumption of a square-root fluence dependence of the photo-induced changes in the complex refractive index of the material. The solid curves are guides to the eye.
