  Configurations of the molecules on the wall of a vacancy, formed by removing
a central and its first and second nearest-neighbor (NN) molecules in solid CO2
with the Pa3 structure, were calculated by the Monte Carlo simulation technique
at T = 0, 100, and 200 K and a nominal pressure of P = 1 bar. It was found that
the deviations of both the center-of-mass and the orientational coordinates of
the molecules from the unperturbed coordinates had a three-fold symmetry about
a body diagonal axis of the crystal. It was also found that a single CO2
molecule, initially placed in the center of the vacancy, was stabilized at a
position close to the vacancy wall. This paper is a continuation of
