Radio Frequency Spectroscopy of Penning Ions: Measurement of Ion and Molecular Lifetimes.
Abstract
The radiative lifetimes of some doublet P(3/2) states of metal atomic ions have been measured in a flowing helium afterglow by using the method of zero field level crossing (Hanle effect). The use of the flowing helium afterglow provides an efficient means for producing the ions to be studied (by Penning Ionization) in an environment where system parameters can be easily modified. The optical emission spectra of I2 obtained in the flowing afterglow has been observed. A pulsed xenon ion laser and its application as a pump source for a tunable dye laser is described. The lifetimes of the rotational levels of the v'=0,1, and 2 levels of the A doublet Delta state of CH have been measured. The rotational lifetimes of the v'=0 level of the B doublet Sigma(-) state of CH have also been examined.
