Mass separated /sup 117/Xe..-->../sup 117/I..-->../sup 117/Te decays were studied on-line by bombarding /sup 104/Pd with 86 MeV /sup 16/O ions and off-line by bombarding /sup 107,109/Ag with 50-70 MeV /sup 12/C. From gamma ray and x ray singles, half-life, excitation function, and coincidence measurements, 26 gamma rays are assigned to the deccay of /sup 117/Xe and 31 gamma rays are assigned to the /sup 117/I decay. The half-lives were measured to be 61 +- 2 sec, 2.22 +- 0.04 min, 62 +- 2 min, and 2.8 x 0.2 h for /sup 117/Xe, /sup 117/I, /sup 117/Te,, and /sup 117/Sb, respectively. Eight new levels are deduced in /sup 117/I and seven new levels in /sup 117/Te. From the Kurie plot of the positron spectrum, the Q/sub E//sub C/(/sup 117/Xe..-->../sup 117/I) was determined to be > or =6.27 +- 0.30 MeV.
