 note = {NO(+) plasma was produced inside a chamber using an EUV source and controlled amount of water vapor was introduced to produce cluster ions. Ion formation started within a minute but the time required for attaining peak concentration for different ions varied from 1 min to 40 min. Positive ions detected for the first time in this experiment were 33(+), 54(+), 66(+), 71(+), 76(+), 83(+), 86(+), 93(+), 94(+), 102(+), 112(+), 117(+), 131(+) (with high concentration) and 19(+), 29(+) and 37(+) (with low concentrations). In addition, a number of other ions were detected with lower concentrations. Concentration of most of the ions was strongly dependent on NO and water vapor pressures. Effect of lower and upper thresholds of chamber pressure, for the production of cluster ions was observed clearly. These pressure thresholds correspond to an altitude range of 50 to 100 km in the ionosphere, where cluster ions have been observed., 資料番号: AA0047901003},
