  A modification of the Gay-Berne potential is proposed which is about 10% to
20% more speed efficient (that is, the original potential runs 15% to 25%
slower, depending on architecture) and statistically more accurate in
reproducing the energy of interaction of two linear Lennard-Jones tetratomics
when averaged over all orientations. For the special cases of end-to-end and
side-by-side configurations, the new potential is equivalent to the Gay-Berne
one.
