3. Show that in an ideal hexagonal-close-packed (hcp) structure, where the atomic
spheres touch each other, the ratio c/a is given by
:-()*
( 8 \ 1/2
= 1.633.
(The hep structure is discussed in Section 7.)
4 The packing ratio is defined as the fraction of the total volume of the cell that is
filled by atoms. Determine the maximum values of this ratio for equal spheres
located at the points of simple-cubic, body-centered-cubic, and face-centered-cubic
crystals.

a. Find the position of the potential minimum and its value there, in terms of o and Eo,
respectively. What do these parameters represent physically about the molecule?
b. Draw a hand sketch of V(r) showing rmin, V(rmin) and where V crosses the r axis.
c. If the atom is disturbed from its equilibrium by a small amount, show that the

frequency of oscillation is w =
d. For molecular nitrogen, the bond length is 1.1 x 10-1°m, the bond (binding) energy is
9.79 eV (15.66 x 10-19 J), the mass is 14 amu = 23.38 x 10-27 kg. In the spectroscopy
laboratory, this vibration is measured to be 8.8 x 1013 Hz. Is this a good model for
the interatomic potential? (Recall o = 2n times frequency in Hz)
where m is the mass of a nitrogen atom.
