1. The problem statement, all variables and given/known data Consider a particle of mass m in a harmonic potential: If the particle is in the first excited state (n = 1), what is the probability of finding the particle in the classically excluded region? 2. Relevant equations 3. The attempt at a solution I sub in and get a wave function: But I don't know how to set my bounds for the normalization integral. I've been advised that the classical limits are: But I'm still stuck.
