From our studies it can be seen that in case of the deformed nuclei suggested
correction gives a non-negligible contribution to the fusion barriers heights and
positions depending on the mutual orientation of the nuclei. The obtained results
suggest that accounting for the curvature correction to the surface energy is essential
when studying the interaction of the deformed nuclei.
