超声喷流氩氢混合团簇特性研究

he average mixed cluster size in different mixing proportion of Ar-CH4 mixed cluster and Ar-H2 mixed cluster in supersonic gas jet was studied by Rayleigh Scattering method at pressures from 20 to 50 atm. It was found that Ar-CH4 mixed cluster could form easily when the mixed argon and CH4 gas are used in gas jet, and the maximum cluster size is achieved when the content of Argon is 50%. The maximum cluster size of Ar-CH4 mixed cluster is larger than either Argon cluster or CH4 cluster. Differ from pure hydrogen cluster which only forms in liquid nitrogen temperature, Ar-H2 mixed cluster can form in room temperature. So this is the first time we get hydrogen cluster in room temperature. While Ar-H2 mixed cluster forms when the content of H2 is higher than 40% and it grows to maximum size when the content of H2 is 60%. Hydrogen (deuterium) mixed clusters introduce heavier Ar element base on hydrogen (deuterium) clusters. It will further accelerate the deuterium ions to higher energy in deuterium clusters laser fusion experiments, so we can get higher neutron yield and fusion efficiency .
