| 英文摘要 | large rare gas clusters ar-n, kr-n and xe-n were produced at room temperature in the process of supersonic adiabatic expansion. the cluster size is examined by a rayleigh scattering a experiment. power variations of the average cluster size (n) over bar (c) with the gas backing pressure p-0 give size scaling as (n) over bar (c) infinity p-0(2.0) resulting in the largest cluster sizes which are estimated in the present work to be about 1.5 x 10(4), 2.6 x 10(4) and 4.0 x 10(4) atoms (the corresponding diameters of the cluster spheres are about 9, 13 and 17nm) for ar, kr and xe, respectively. a time resolving rayleigh scattering experiment was conducted to investigate the time evolution of cluster formation and decay processes. a surprising two-plateau structure of the time evolution characteristic of cluster formation and decay processes of kr and xe clusters was revealed as compared with a "normal" single structure for the case of ar gas. in the second plateau, the intensity of the scattered light is enhanced greatly, by even as much as 62 times, over that in the first plateau, indicating a significant increase in cluster size. this finding supports the importance of nuclei in the gas condensation process and may be helpful for further insight into the phenomenon of clustering. |
