  The $\alpha$-optical potential is one of the key input parameters used to
measure the reaction rate of the ($\gamma,\alpha$)-process using the
Hauser-Feshbach(HF) statistical model and the principle of detailed balance.
$\alpha$-elastic scattering experiment on $^{113}$In $p$-nucleus was carried
out in the energy range E$_{lab}$=26$-$32 MeV. The vacuum evaporation technique
was used to prepare the $^{113}$In target~($\sim$86 $\mu$g/cm$^2$). An
energy-dependent local optical potential parameters set was obtained by
analysing the experimental elastic scattering angular distribution data. The
local potential parameters are extrapolated for lower energies and are used to
measure the $^{113}$In($\alpha,\gamma$) reaction cross-section.
