Study of Collisionhyphen;Induced Phenomena with a Dempster Mass Spectrometer. II. Experimental

摘要

A method for the study of collisionhyphen;induced phenomena in a Dempster mass spectrometer is demonstrated. Experimental studies are made of the following reactions, and their reaction cross sections are determined at 1000 V ionhyphen;accelerating potential:Ar2plus;plus;Arrarr;Arplus;plus;Arplus;sgr;equals;3.6times;10minus;16cm2COplus;plus;CO2rarr;Cplus;plus;Oplus;CO2sgr;equals;6.6times;10minus;17cm2N2plus;plus;N2rarr;Nplus;plus;Nplus;N2sgr;equals;3.5times;10minus;17cm2N2Oplus;plus;N2Orarr;NOplus;plus;Nplus;N2Osgr;equals;6.3times;10minus;17cm2CO2plus;plus;COrarr;Cplus;plus;lpar;Oplus;rpar;plus;lpar;COplus;rpar;sgr;equals;1.4times;10minus;17cm2.The value of 1.0times;10minus;17cm2for the reactionCOplus;plus;COrarr;Cplus;plus;Oplus;COwas used for calibration. In addition, the total collision cross sections for the following systems were determined:COplus;in COsgr;Tequals;2.4times;10minus;16cm2Oplus;in COsgr;Tequals;5.0times;10minus;17cm2Cplus;in COsgr;Tequals;1.8times;10minus;16cm2Arplus;in Arsgr;Tequals;2.2times;10minus;15cm2Ar2plus;in Arsgr;Tequals;1.2times;10minus;15cm2.
