3. Consider a monatomic linear with equilibrium separation a. Suppose the outer
electrons (of mass m) in a given atom move with a displacement different from that
of the corresponding ion core (of mass M). Let the displacement of the ion core s be:
Us = uei(Ksa-wt)
and the displacement of the center of mass of the outer electrons associated with ion s
be:
V = vei(Ksa-wt)
Each ion core is assumed to interact only with its own outer electrons with a force
proportional to the displacement of the electron distribution from the nucleus, and the
force constant is C₂. However, neighboring electron distributions interact with a force
constant C₁.
a) Show that
-w² Mus = C₂ (vs - Us)
-w²mvs = C₂ (us - Vs) + C₁ (Vs+1 + Vs-1-2vs)
b) Substitute for the displacements, and solve the resulting simultaneous equations.
Find an expression for w².
c) Take the limit as m → 0 (the mass of electrons is much smaller than that of the ion
core), and show that the dispersion relation for the acoustic mode is…

- 1. The Zeeman effect refers to the splitting of certain orbitals when the atom is placed in an external magnetic field. In the absence of an external field (and neglecting spin-orbit coupling) all the I states corresponding to a particular n state have the same energy – this phenomenon is referred to as degeneracy. A magnetic field partially "lifts" this degeneracy by causing each l 0 state to split into 21 +1 substates denoted by mi, with the modified energy given by the formula -13.6 En.m = eV + m¡UgB n2 where ug = 5.78 * 10-5eV/T. a.
