# Perturbation Theory

A particle of mass m is in the ground state in the harmonic oscillator potential

V(x) = (1/2)Kx^2

A small perturbation (beta)x^6 is added to this potential.

a) What are the units of beta?

b) How small must beta be in order for perturbation theory to be valid?

c) Calculate the first-order change in the energy of the particle.
