VAZQUEZ-LOPEZ, C; ESPINOSA, G; GOLZARRI, J.I  and  JIMENEZ-SANDOVAL, S. Morphological and raman effects on ²⁵²Cf irradiated diamond. Rev. mex. fis. [online]. 2008, vol.54, suppl.1, pp.54-56. ISSN 0035-001X.

Radiation damage produced by the incidence of fission fragments from a californium (²⁵²Cf) source into diamond is characterized by atomic force microscopy and Raman spectroscopy. In comparison with the original non irradiated surface, it was found cavities and hillock-like regions. By micro-Raman spectroscopy, it was revealed changes in the crystalline structure: there are graphite-like regions and nano structured diamond regions.

Keywords : diamond; atomic force microscopy; Raman spectroscopy; nuclear tracks.
