Micro-Raman study on self-irradiated minerals

Micro-Raman spectroscopy was used to evaluate the radiation damage in metamict form of gadolinite and defects formed in halite single crystals. The metamict mineral of gadolinite was investigated in order to study its structural variation in metamict form and recrystallized form. However, types of defects which are originally present in halite crystals responsible for its gradual colour variation are identified using Micro-Raman spectra (author)
