RATE COEFFICIENT FOR X' '2X]-X2' 'X IN NEON AND ARGON

A method is described of determining three-body conversion coefficients for the production of homonuclear diatomic ions. The technique involves ion sampling from the positive column of a dc discharge. For neon, values of the rate coefficient vary from 5.7-8.9×10-32 cm6/sec depending on the values of a number of experimental parameters. In argon values range from 3.0-4.7×10-31 cm6/sec. The present results are compared with values obtained using other techniques. © 1969 The American Physical Society.
