Finding Ground State Wave Functions: Tips & Tricks

[LAHLH]

Hi,

If I have the Hamiltonian: $H=(1/2)p^2+(1/24)\lambda(x^2-v^2)^2$ what is the best way to find the ground state wave functions $\psi(x)$. I was thinking this sort of looks like the harmonic osscilator, so maybe a clever change of variables could do the trick? or some form of perturbation perspective?
