Query: Nuclear Force in the Skyrme Model: Quasistatic Approach   Dynamics of two-Skyrmion systems is studied in the quasistatic approach. The
quasistatic approach enables us to formulate the collective coordinate
quantization of two-Skyrmion systems consistently with the 1/Nc expansion. By
constructing quasistatic field configurations for largely separated two
Skyrmions, their energies are computed for three independent relative
orientations of the Skyrmions in the isospin space. The obtained energies are
much lower than those for the product approximation. In particular, the
repulsion in the two-pion range is considerably reduced.
