Neutron Transmission Measurements and Resonance Parameters in Cd

Neutron transmission measurements for cadmium have been determined from 14.5 ev to 11 kev. These data were taken with 0.04 to 0.07 μsec/meter resolution using the Materials Testing Reactor fast chopper. Isotopic assignments have been made to those resonances which are due to ${\mathrm{Cd}}^{111}$ and ${\mathrm{Cd}}^{113}$ by using a sample enriched in ${\mathrm{Cd}}^{111}$ and another sample depleted in ${\mathrm{Cd}}^{113}$. Breit-Wigner parameters have been obtained up to 215 ev and give values for $\frac{{{\overline{\Gamma }}_n}^0}{D}$ of (0.33±0.09)×${10}^{-4\mathrm{}}$ for ${\mathrm{Cd}}^{111}$ and (0.43±0.13)×${10}^{-4\mathrm{}}$ for ${\mathrm{Cd}}^{113}$.
