Physical Process
Tunneling Ionization is a QM phenomenon; a non-zero probability event for observing a particle escaping from the deformed Coulomb potential barrier, obviously this phenomenon is forbidden by classical laws, as in the classical picture an electron does not have sufficient energy to escape.
As the Coulomb potential barrier is lowered, its width decreases, and this in turn increases the probability of electron tunneling through the barrier. The ADK probability formula gives the expression for the probability of tunnel ionization.

Famous quotes containing the words physical and/or process:
“Even the simple act that we call “going to visit a person of our acquaintance” is in part an intellectual act. We fill the physical appearance of the person we see with all the notions we have about him, and in the totality of our impressions about him, these notions play the most important role.”
—Marcel Proust (1871–1922)
“Yet I doubt not through the ages one increasing purpose runs,
And the thoughts of men are widened with the process of the suns.”
—Alfred Tennyson (1809–1892)
