  We study the unstable modes of the baryon number two hedgehog of the Skyrme
model on a three dimensional spatial lattice. An expansion of the Skyrme
Lagrangian around the hedgehog configuration provides the equations of motion
for the fluctuation fields solvable numerically via a relaxation method. We
find the negative energy modes and, by evolving the excited hedgehog in time, a
breakup into two separated solitonic configurations is obtained. Different
paths of descent for the receding Skyrmions are presented and the possibility
of determining the metric structure of the collective-coordinate manifold is
discussed.
