title: Photoabsorption cross section of C70 thin films from visible to vacuum ultraviolet.
abstract: Absolute photoabsorption cross sections of C(70) thin films were determined for hv values from 1.3 to 42 eV using photon attenuation. The spectrum showed a prominent peak of 1320 Mb at 21.4 eV with several fine structures mostly due to sigma-->sigma(*) single-electron excitation. The complex refractive index and complex dielectric function were calculated up to 42 eV with Kramers-Kronig analyses. From the present data of C(70) thin films, the cross section curve of molecular C(70) was calculated using the standard Clausius-Mossotti relation dealing with correction of the local electromagnetic field, with a plausible assumption that the anisotropy in molecular structure of C(70) was smeared out by molecular rotation at room temperature.
