内容記述 | Recent observations of the ionized clouds using ionosondes in cesium release experiments with the rockets, K-9M-33, K-9M-39 and K-9M-42, suggested that the total electron number in the cloud increased with time after release due to photoionization by solar ultraviolet radiation. In this report, the two ionization prosesses, thermal-and photoionization, of chemical cloud of various alkali species have been considered. The photoionization probability of an cesium atom by dayttime solar flux has been estimated to be about 1.2 × 10^<-4>/sec from the results of radar observation, while the theoretical estimation was about 2.8 × 10^<-4>/sec. The ionization rate due to heats associated with gas evaporation during initial period, which is considered to be 2.0 ~ 4.0 10, i_0 very low in comparison with that of photoionization during the diffusion except the time period of an initial few seconds after gas release. The comparison between the theoretical estimation and the real observational data concerned with ionization process provides us with some fundamental parameters of the ionized clouds necessary for planning a similar rocket experiment in the future. | |||||
