Isotope effect in the predissociation of the c 4Σ-sub(u) state of O2+
- 1. Paris-11 Univ., 91 - Orsay (France)
Description
The dissociation of the upsilon = 0 and upsilon = 1 vibrational levels of the c 4Σ-sub(u) state of O2+ has been investigated using a photoion-photoelectron coincidence method. A different branching ratio for the fragmentation into O+(4S0) + O(3P) and O+(4S0) + O(1D) has been observed for 16O2+ and 18O2+ in the upsilon O level. This isotope effect shows that the predissociation to the O+(4S0) + O(1D) adiabatic limit is mainly due to the tunnelling through the c-state potential barrier; no spin-orbit or rotational interaction seems to be involved.
