Experimental photodissociation and/or photodetachment of atmospheric negative ions: Initial results on O2(-) and CO3(-)
Abstract
A drift tube mass spectrometer apparatus with a laser photon source has been constructed to measure photodissociation and/or photodetachment cross sections of atmospheric negative ions. Values for the cross sections of the negative ions of molecular oxygen and carbon trioxide are in good agreement with published results. Most of the data obtained for the discrete energies available to the Kr ion laser represent new results. These results reinforce the existing evidence of substantial structure in the spectrum of the negative carbon trioxide ion photodestruction cross section.
