We present results on the effect of potassium co-adsorption on the ESD from CO and NO on Ni(ll1) at 90 K. K co-adsorption strongly affects the yields of positive ions and alters their electron beam energy dependence. At a K-coverage of 6, = 0.25 and saturation coverages of CO or NO, the strong O+ ES
