Textbook Problem

A physics student caught breaking conservation laws is imprisoned. She leans against the cell wall hoping to tunnel out quantum mechanically. Explain why her chances are negligible. (This is so in any classical situation.)

To determine

The reason of negligible possibility of a student to tunnel out quantum mechanically leaning against the cell wall.



Since as we know that in the movement of a particle which is quantum in size and mechanical in nature the function of wave varies smoothly.

And this movement inside the nucleus will be from one side of a barrier of potential energy to another side of the barrier.

At the inner half of barrier, the function of wave will not become zero but reduces exponentially, and we will not able to locate the particle at the barrier's inner half.

Since the chances of locating a particle is in a relation to the wave function square, and thus there are very low possibility of locating a particle at the outer side of barrier, that leads to the conclusion that the particle can pass through the barrier...
