Experimental evidence of dynamic trapping in the scattering of H from Pd (110) (original) (raw)

We have performed H2 (D2) diffraction experiments on a Pd(110) surface, revealing that the total reflectivity of Pd(110) is comparable to other reactive systems, yet H2 (D2) diffraction patterns deviate significantly, lacking any observed diffraction peaks, including the specular one. This anomaly is attributed to dynamic trapping, supported by classical dynamics calculations based on precise ab initio potential energy surfaces, reinforcing the role of dynamic trapping mechanisms in surface chemistry and molecular interactions.
