Chapter 7
•
In chapter 6 we learned about a set of rules for
quantum mechanics. Now we want to apply them to
various cases and see what they predict for the
behavior of quanta under different conditions.
Free Particle:
We already looked at a special case of this
for the 2-slit experiment where the free particle was in an
eigenstate of momentum…it had a well defined
momentum and therefore wavelength.
Bound Particle: Many particles in nature are not free but
bound in a system.
Electron in an atom.
Proton in a nucleus
Atom in a lattice.
•
Bound Systems are perhaps the most interesting cases
for us to consider. We see much of the interesting
features of quantum mechanics.
However, bound systems can be very complicated (even
for advanced physics courses!)
Uranium Atom…no way of solving that in an exact
way…in fact you get much beyond helium and it gets
very hard.
We will make a number of simplifying assumptions
(approximations). Although these are approximations do
not significantly alter our results…all the interesting
features of quantum mechanics will still be there.
