Abstract

Crossed beam studies of K -D₂O collisions have been carried out for laboratory K beam energies from 10 to 200 eV. The only ionic products observed were K⁺ and OD^-. The reaction Q thresholds obtained from the measured K⁺ energy distributions show that the K⁺ ion onset corresponds to the D (²S) + OD^- (¹Σ) limit of D₂O^- at 3.28 eV. Q here is defined as the excess of product over reactant kinetic energies. This result suggests that any minimum in the ²A₁ state of D₂O^- (on the D- OD^-coordinate axis) may be shallow ≲0.1 eV in depth.
