10.1 correspondence between time-dependent and time-independent solutions

The time dependent Schrödinger equation is

−{{ℏ}^{2}\over 2m} {{∂}^{2}\over ∂{x}^{2}}ψ(x,t) + V (x)ψ(x,t) = {ℏi∂\over ∂t} ψ(x,t).
(10.1)

As we remember, a solution of the form

ψ(x,t) = ϕ(x){e}^{−iEt∕ℏ}
(10.2)

leads to a solution of the time-independent Schrödinger equation of the form

−{{ℏ}^{2}\over 2m} {{∂}^{2}\over ∂{x}^{2}}ϕ(x) + V (x)ϕ(x) = Eϕ(x).
