We measured thick-target yields of [sup 126,128,130]I from bombardments of natural Te targets with 15-, 30-, 45-, and 50-MeV protons, together with iodine production cross sections for 1.85- and 5.0-GeV protons. Using these data, we have estimated the relative cosmic-ray induced production of [sup 126]Xe, [sup 128]Xe, and [sup 130]Xe in Te ores. These quantities are significantly different from those used previously in a determination of the ratio of the double-[beta] decay half-lives of [sup 130]Te and [sup 128]Te, and as a result the cosmic-ray correction is smaller than previously assumed. A revised correction of cosmic-ray produced xenon can change the half-life ratio by about 6%. This quantity is of importance because it can be used to set a limit on the 0-[nu] double-[beta] decay mode.
