Fission Product Yields (FPY) have historically been one of the most observable features of the fission process. They are known to have strong variations that are dependent on the fissioning species, the excitation energy, and the angular momentum of

The cross section for neutron capture in the continuum region has been difficult to calculate accurately. Previous results for $^{238}\mathrm{U}$ show that including an $M1$ scissors-mode contribution to the photon strength function resulted in very
