Homework Statement
Consider a 1-dimensional linear harmonic oscilator. Any measurement of it's energy can either return the value of ħw/2 or 3ħw/2, with equal probability. The mean value of the momentum <P> at the instant t=0 is
<P> = (mħw/2)1/2
Find the wave function ψ(x,0) for this state.
Homework Equations
The Attempt at a Solution
I started by assuming that the wave function would be something of the kind:
ψ(x,0) = α|ϕ0> + β|ϕ1>
Since the probability of measuring the energy for n=0 and n=1 is the same I concluded that α=β

I think my way of solving the problem is correct, however the result doesn't make sense... If someone could give me a hint about where I might have gone wrong I'd appreciate. Thanks.
