Atoms tunnelling through a metal surface

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of atomic tunneling through metal surfaces, exploring whether there is experimental evidence to support this claim. Participants express varying levels of understanding and seek references to substantiate the existence of such tunneling effects.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant inquires about experimental proof of atoms tunneling through metal surfaces and requests references for further reading.
  • Another participant expresses skepticism about the extent of atomic tunneling, suggesting limitations based on a provided link.
  • A different participant questions the notion that any particle could be exempt from tunneling, implying a universal property of quantum mechanics.
  • One participant notes that while hydrogen exhibits tunneling behavior, heavier atoms experience a rapid decrease in tunneling rates due to their mass, suggesting a distinction in behavior based on atomic weight.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the extent of atomic tunneling through metal surfaces, with multiple competing views and uncertainties expressed regarding the phenomenon.

Contextual Notes

There are unresolved assumptions regarding the conditions under which tunneling occurs and the specific contexts of atomic behavior in relation to mass and metal surfaces.

Hey guys.i have heard it has been experimentally proved that even atoms can tunnel through a metal surface.I tried searching all over the web but just could not get any references on that.So,is that true?if somebody know where i can read more about that experimental proof,please point it out.

thanks a lot in advance.

I don't think that tunneling of atoms goes further then this:

Im not sure how anything could not have the ability to tunnel. ?
 
Hydrogen tunnels all over the place. Although it still is 'mostly' classical, in that a classical model will usually account for most of its motion, statistically speaking.

But since tunneling rates drop off exponentially with mass, the effect disappears quickly for heavier atoms.
