    • The search algorithm, described in Ref. [19], involves circling around the location of the adsorbate. The time the tip spends directly over the H can be made arbitrarily small.

    • The high temperature form assumes that multiphonon processes are important. This is justified for temperatures near the onset of classical diffusion (60 K).

    • note
    • The onset of apparently classical behavior corresponds to the dominance of transitions between vibrational excited states; the tunneling rate increases rapidly with the vibrational quantum number.
