摘要：

The alpha-decay chain Xe-109 -> Te-105 -> Sn-101 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 Xe-109 and Te-105, respectively. Two alpha-decay transitions were observed from Xe-109 with Q(alpha) values of 4067 +/- 10 and 4217 +/- 8 keV. One transition between the ground states of Te-105 and Sn-101 was observed with a Q(alpha) value of 4889 +/- 6 keV. Using the measured half-lives, branching ratios, and Q(alpha) values the reduced alpha-decay widths, delta(2), were determined. Comparison of the delta(2) value for Te-105 with Po-213 indicates a "superallowed" character in the alpha emission of Te-105.
