This isn't actually a homework question/problem, but a conceptual problem that i've been having regarding tunneling.
Can someone please tell me what will happen to a particle's energy if a particle tunnels through some potential barrier, given that the particles energy is less than that of the potential barrier. I would assume that the particles kinetic energy would deffinitely decrease, but how could you find by how much it decreases? its not simply (V - Uo), is it? (where V is the particles KE and Uo is the potential of the barrier).
Also, if the potential barrier has lower energy than the energy of the particle, how does the energy of the particle change once it crosses the barrier?
If someone could please help me out with understanding this I would appreciate it greatly.
