They are both split into three … WebAug 11, 2024 · Consider a particle of mass m and energy E moving in the following simple potential: (4.1.1) V ( x) = { 0 for 0 ≤ x ≤ a ∞ otherwise. It follows from Equation ( [e5.2]) that if d 2 ψ / d x 2 (and, hence, ψ) is to remain finite then ψ must go to zero in regions where the potential is infinite. Hence, ψ = 0 in the regions x ≤ 0 and x ≥ a.
