A study of the gamma-ray de-excitation following the beta decay of /sup 118/Ag using the TRISTAN on-line isotope separator is reported. Gamma-ray singles, gamma-gamma coincidence, and gamma-ray multiscale measurements were made using Ge(Li) detectors. A total of 52 gamma rays were observed in the decay of /sup 118/Ag. Thirty-eight of these were placed in a level scheme for /sup 118/Cd consisting of 20 excited states up to 3382 keV. Gamma-ray multiscale measurements indicated that /sup 118/Ag has an isomeric state at 128 keV with a half-life of 2.0 +- 0.2 seconds. The ground state half-life is 3.76 +- 0.15 seconds. The /sup 118/Ag decay scheme is compared with a previous decay study. The level scheme systematics are discussed and compared with recent collective model calculations.
