摘要

Abstract

Using Raman and X-ray photoelectron spectroscopy

we delineate the bond and defect structures in nuclear block graphite (NBG-18) under neutron and ion irradiation. The strengthening of the defect (

) peak in the Raman spectra under irradiation is attributed to an increase in the topological

-hybridized defects. Using transmission electron microscopy

we provide evidence for prismatic dislocations as well as a number of basal dislocations dissociating into Shockley partials. The non-vanishing

peak in the Raman spectra

together with a generous number of dislocations

even at low irradiation doses

indicates a dislocation-mediated amorphization process in graphite.
