the particle m and will thus be independent of the potential well. We can thus exploit the fact that ψ0 is the ground state of a harmonic oscillator which allows us to compute the kinetic energy very easily by the virial theorem for a harmonic oscillator wave function: T = E o/2=¯hω/4.But what ω corresponds to our trial wave function a parameter? Fortunately this is easy since a = mω/¯h ...
