Pa. Hatherly et al., SYMMETRY EFFECTS IN SITE-SPECIFIC FRAGMENTATION OF CARBON-DIOXIDE, Journal of electron spectroscopy and related phenomena, 79, 1996, pp. 407-410
Results are presented for the dissociation dynamics of carbon dioxide
following the removal of a 1s electron from the C and O cores. A state
-selected triple coincidence technique is used in combination with a m
onochromatic soft x-ray source and the apparatus aligned both parallel
and perpendicular to the radiation polarisation vector. The data show
, for the CO+ + O+ channel, dissociation preferentially perpendicular
to the polarisation vector for excitation at the C 1s edge, but parall
el at the O 1s edge. The same behaviour is seen for the O+ + C+ + O+ c
hannel, although this channel is weak following O 1s excitation.
