7th grade Ground State Harmonic Oscillator problem

Click For Summary
SUMMARY

The discussion focuses on calculating the probability of finding a ground state harmonic oscillator beyond its classical turning points using the wave function Psi n(q) = (alpha/pi)^(1/4) exp(−alpha*q^(2)/2). The classical turning points are defined as the points where the energy E equals the potential V(x), which is represented by a parabolic function. The solution involves integrating the square of the wave function |psi|^2 outside the classical turning points to determine the probability.

Homework Statement



Calculate the probability for finding the ground state harmonic oscillator
beyond its classical turning points.

Homework Equations



Psi n(q) = (alpha/pi)^(1/4) exp(−alpha*q^(2)/2), where alpha = (kμ)^(1/2)/h bar

The Attempt at a Solution



i know it's going to be probability = 1-intergral of psi*psi, but I'm not sure what the boundaries are.

7th grade? Anyway, the classical turning points are just the points x where E=V(x). Here V(x) is a parabola, so there will be two solutions, one the negative of the other. You'll want to integrate |psi|^2 outside this region.
