Angular momentum: summary
Eigenfunctions
of
and
are labeled by m and l:
For a given value of l, there are 2l+1 values of m:
Generally, half-integer values are also allowed (but not for orbital angular moment).

Time-independent perturbation theory
Nondegenerate perturbation theory General formalism of the problem: Suppose that we solved the time-independent Schrdinger equation for some potential
Lecture 3
Two-particle systems
State of the two-particle system is described by the wave function
The Hamiltonian for the two-particle system is
Of course, as usual, the time evolution of the system is described by the Schrdinger
equation:
The probability
