The magnetic dipole interaction of two spin 1/2 particles is described by the potential
V = A
where r is the distance between the two particles.
a. Show that this can also be written as
S?r2 – 3(5. 72
V = 2A
where S = (1 + 2).
b. What are possible the interaction energies, if the distance between the two particles
is fixed d?
c. Assume that the two spin 1/2 particles are at a fixed distance d from each other as in
part a, and that at t = 0 one of the spins is along the direction of the vector from particle
1 to particle 2, and the other is in the opposite direction. After how much time will the
directions of the spins be flipped?
