Now let's see what is going on, when a particle passes inside the box WALL. Then E is less than U and k being square root from now negative number becomes IMAGINARY, thus making ikx REAL number, and we have pure exponential dectrease (or increase depending where particle originally was - inside or outside)of probability inside wall. Because exponent never drops to zero, thus there is always a chance to find a particle outside regardless how thick or how strong are the walls. That is the nature and explanation of quantum tunnelling - electrons, protons, alpha particles, atoms and molecules can penetrate via variety of microscopic walls and result in radioactivity, various decay processes, in diffusion, in chemical reactions, etc.
