In the article, as a solution to the Schödinger equation, the function is given (in Maple notation):

Psi (t): = psi*exp(-(2*Pi*I*E/h)*t);

If one then takes (|Psi(t)|)**2, one would expect the integral for t from zero to infinity to be equal to 1. The integral (in Maple notation):

Int ((abs(psi*exp(-(2*Pi*I*E/h)*t)))**2, t = 0 .. infinite);

however, is equal to infinity. What error did I make?
