What is the probability of finding a particle outside of the classically allowed region in the ground state of the harmonic oscillator? The classical energy of a harmonic oscillator with amplitude a is E = =ka? = mwa3, so the classically allowed region is - 2E 2E mw Hint: Use the error function erf(x) = 3 / exp[-x']dr with erf(co) = 1 and erf(1) = 0.843
