The alpha-decay chain 109Xe-->105Te-->101Sn was identified at the Holifield Radioactive Ion Beam Facility. Advances in digital electronics have made possible the identification of both alpha emitters in the same experiment despite the disparate half-lives of 13+/_2ms and 620+/_70ns for 109Xe and 105Te, respectively. Two alpha-decay transitions were observed from 109Xe with Q/alpha values of 4067 +/_ 10 and 4217 +/_ 8keV. One transition between the ground states of 105Te and 101Sn was observed with a Q/alpha value of 4889 +/_6keV. Using the measured half-lives, branching ratios, and Q/alpha values the reduced alpha-decay widths, delta squared, were determined. Comparison of the delta squared value for 105Te with 213Po indicates a "superallowed" character in the alpha emission of 105Te.
