Nuclear Charge Distribution in Fission: Independent Yields ofI132,I133, andI134from Thermal Neutron Fission ofU233

Independent yields of ${}_{}{}^{132}{}_{}{}^{}\mathrm{I}$, ${}_{}{}^{133}{}_{}{}^{}\mathrm{I}$, and ${}_{}{}^{134}{}_{}{}^{}\mathrm{I}$ have been measured from thermal-neutron-induced fission of ${}_{}{}^{233}{}_{}{}^{}\mathrm{U}$. The yields, each expressed as the ratio of iodine independent yield to iodine cumulative yield, are 0.06±0.03, 0.21±0.03, and 0.370±0.013 for ${}_{}{}^{132}{}_{}{}^{}\mathrm{I}$, ${}_{}{}^{133}{}_{}{}^{}\mathrm{I}$, and ${}_{}{}^{134}{}_{}{}^{}\mathrm{I}$, respectively. Values of $Z_p$ estimated from these yields with the assumption that charge distribution can be represented by a Gaussian curve with standard deviation $\sigma$ of 0.59±0.06 are ${51.58}_{-0.30\mathrm{}}^{+0.21\mathrm{}}$, ${52.02}_{-0.12\mathrm{}}^{+0.10\mathrm{}}$, and 52.33±0.03 for ${}_{}{}^{132}{}_{}{}^{}\mathrm{I}$, ${}_{}{}^{133}{}_{}{}^{}\mathrm{I}$, and ${}_{}{}^{134}{}_{}{}^{}\mathrm{I}$, respectively. The values of $Z_p$ are consistent with those previously reported for other chains in this mass region.
