Description
  • Abstract en The Crystallinity of ices, amorphous and crystalline, can be altered not only by heat but also by irradiation of UV-rays or charged particles. In this work, the effect of UV-irradiation on the crystallinity of CO2 ice was investigated by using a transmission electron microscope. A crystalline CO2 ice was produced by annealing amorphous CO2 ice. We found that UV-ray irradiation of CO2 crystals at approximately 10 K does not cause amorphization in contrast to the reported amorphization of crystalline water ice below 70 K. We discuss the difference based on the expected UV photochemistry of CO2 ice.
