  A model-independent technique was used to determine the $\gamma$-ray Strength
Function ($\gamma$SF) of $^{56}$Fe down to $\gamma$-ray energies less than 1
MeV for the first time with GRETINA using the $(p,p')$ reaction at 16 MeV. No
difference was observed in the energy dependence of the $\gamma$SF built on
$2^{+}$ and $4^{+}$ final states, supporting the Brink hypothesis. In addition,
angular distribution and polarization measurements were performed. The angular
distributions are consistent with dipole radiation. The polarization results
show a small bias towards magnetic character in the region of the enhancement.
