Heterogeneous reactions between ions NH3+and NH+andhydrocarbons adsorbed on a tungsten surface.Formation of HCN+in NH+-surface hydrocarbon collisions

Popis výsledku v původním jazyce

tInteraction of NH3+(ND3+) and NH+with a hydrocarbon-covered tungsten surface kept at room tempera-ture or heated to 150 and 300C showed a series of reactions between the projectile ion and hydrocarbonsadsorbed on the tungsten surface. Collisions with NH3+showed formation of NH4+, HCNH+, and CH2NH2+,with NH4+strongly prevailing at low incident energies of the projectile ion. Analogously, collisions withND3+showed formation of ND3H+, HCND+, and CH2ND2+with dominant contributions of ND3H+at lowincident energies. No formation of HCN+(DCN+) could be positively identified. In reactions with NH+, for-mation of HCN+was clearly observed; the dependence of the normalized yield of HCN+on incident energyindicated a threshold at about 40 eV which might be due to an activation energy or an endothermicity ofthe surface reaction of about 2.4?3.2 eV.
