摘要：

Substantial changes in the electronic and vibrational properties of crystalline C-60 modified by laser irradiation are reported. Ultraviolet photoemission identifies new states relative to C-60. Electron energy loss spectra indicate broadening of interband transitions with the gap remaining unchanged upon laser modification. Intermolecular Raman scattering exhibits one strong mode at 115 cm(-1) and two previously unreported weaker bands centered at 85 and 140 cm(-1). Comparison of the observed vibrational and electronic states with calculations for dimers and infinite chains indicate the laser modified films consist primarily of dimers.
