I'm trying to calculate the expectation value of the momentum squared (p^2) of the harmonic oscillator ground state.(adsbygoogle = window.adsbygoogle || []).push({});

The integral involves the second derivative of a Gaussian (exponential of a negative squared term)

Then the integral involves, after working it out, an x^2 term times exp(-x^2).

I tried this by integrating by parts but it gets me no where. Am I missing something???
