18. Doubly-ionized lithium (Z = 3) undergoes a transition from the n = 2 to the n =] state by emission of a single photon. The photon is absorbed by a system constructed of an electron in a one-dimensional harmonic oscillator potential that is initially in its ground state. What are the two largest possible values of the characteristic frequency wo of the harmonic oscillator that absorbed the photon?
