| Research Abstract |
In order to simulate high-temperature gas reactions by asteroid's impact on Titan (satellites and planets), the impact reaction experiment by use of a 2 stage light gas gun has been carried out. A policarbonate bullet is accelerated to 6.5 km/s and hits an iron (water + iron or water + hexane + iron) target, by which many kinds of carbon clusters are produced. Here, sack-like nano-carbons and polymer-encapsulated nano-carbons are successfully produced. From emission spectrum of CN molecules in the hot plume, CN rotation temperature is about 4600 K and CN life-time is about 20 us. Produced carbon samples are refluxed by pure water and dabcylized. The samples are analyzed by a HPLC. As a results, we can confirm production of amino acids (glycine, alanine and serine).
