# Particle in a box and the Harmonic Oscillator

Please read the attached file for complete description of the problem.

Consider the particle of mass subject to a one-dimensional potential of the following form:

V(x) = 1/2 kx^2 for x>0

V(x) = + infinity for x < 0

This is a combination of the particle in a box and the harmonic oscillator that might be a better model for real diatomic than the standard harmonic oscillator. On the right side of x = 0, the Hamiltonian is exactly the same as a harmonic oscillator Hamiltonian. The hard wall at x = 0, however, introduces a boundary condition. Use what you have learned about both the ordinary harmonic oscillator and particle in a box boundary conditions to answer the following questions.

a) what does this boundary condition require the wave function to do at x = 0?

b)

c)

d)

e)
