In the QM Hamiltonian, I keep seeing h-bar/2m instead of p/2m for the kinetic energy term. H-bar is not equivalent to momentum. What am I missing here?

Actually, gang, I did a little more fishing and came across the answer to my question. For anyone that's interested, here's the link.

Look under this section: Kinetic energy in quantum mechanics
