摘要：

The formation of carbon dioxide molecules from D2O(H2O)/CO binary ice induced by UV irradiation was studied experimentally. The measured conversion rate of CO CO2 to is about one order higher than previously reported rates. Our results imply that CO2 formation by the UV process is efficient even in a quiescent dense cloud.
