Interaction of Negative Muons with Iodine

The interaction of negative muons with iodine was studied radiochemically. The yield of the ${\mathrm{I}}^{127}({\mu }^{-}, \nu ){\mathrm{Te}}^{127}$ reaction was determined to be 8.2±1.6 percent. The sum of the yields of all antimony isotopes is approximately 1 percent. From the yield of 58-day ${\mathrm{Te}}^{125m}$ and upper limits to the yields of 104-day ${\mathrm{Te}}^{123m}$ and 6-day ${\mathrm{Te}}^{118}$, yield distribution curves were drawn to fit the extremes of the experimental errors. The multiplicity was thus determined to be 1.7±0.4 neutrons per muon captured. A yield distribution curve which best fits the data is presented.
