A particle is in the ground state of the harmonic oscillator with classical frequency , when suddenly

Question:

A particle is in the ground state of the harmonic oscillator with classical frequency ω, when suddenly the spring constant quadruples, so ω' = 2ω, without initially changing the wave function (of course, Ψ will now evolve differently, because the Hamiltonian has changed). What is the probability that a measurement of the energy would still return the value ћω/2? What is the probability of getting ћω?
