ABSTRACT
Systems described by a time–independent potential energy function, V(r, t) = V(r), are the subject of quantum statics. Such systems may be studied by the time–dependent Schrödinger equation H Ψ = i ℏ ∂ Ψ ∂ t https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429136528/397e01c1-e101-4a47-b552-a910642bbb8c/content/eqn16_1.tif"/>
