摘要：

We report on two experiments on carbon tetrachloride. CCl4 was pressurized to 4.9 GPa and irradiated with 20 keV hard X-rays for 4 h and 8 h respectively. We observed a greenish yellow material form in the irradiated regions. In the second experiment, the same irradiated sample was left pressurized for 4 weeks. The irradiated regions consolidated and Raman spectra of these spots displayed strong Cl-2 lines. (C) 2013 Elsevier B. V. All rights reserved.
