Understanding the Low-Energy Enhancement of the $\gamma$-ray Strength Function of ${}^{56}$Fe

M. D. Jones, A. O. Macchiavelli, M. Wiedeking +27

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 usin…
