  Semi-empirical mass formula of the atomic nucleus describe binding energies
of the nuclei. In the simple form of this formula, there are five terms related
to the properties of the nuclear structure. The coefficients in each terms can
be determined by various approach such as fitting on experimental binding
energy values. In this study, the surface energy coefficient in the formula
which is a correction on total binding energy has been obtained by a method
that is not previously described in the literature. The experimental fission
barrier energies of nuclei have been used for this task. According to the
results, surface energy coefficient in one of the most conventional formula has
been improved by a factor 3.4.
