Ge(Li) detectors have been used to perform singles, coincidence, and angular correlation measurements on ..gamma.. rays present in the decays of 2.5-h /sup 117/Cd/sup g/(1/2/sup +/) and 3.4-h /sup 117/Cd/sup m/(11/2/sup -/). A total of 112 of the 114 ..gamma.. rays observed in the decay of /sup 117/Cd/sup g/ and all 71 of the ..gamma.. rays observed in the decay of /sup 117/Cd/sup m/ have been placed in a level scheme consisting of 46 excited states. A total of 51 different ..gamma..-..gamma.. cascades were measured at 90/sup 0/ and 180/sup 0/. The ..beta.. branchings from /sup 117/Cd/sup g/ to /sup 117/In/sup m/ and /sup 117/Cd/sup m/ to /sup 117/In/sup g/ were determined to be 20.4% and <1%, respectively. The thermal neutron cross sections for the production of /sup 117/Cd/sup g/ and /sup 117/Cd/sup m/ were determined to be 43 +- 2 mb and 8 +- 1 mb, respectively. Spin and parity assignments for the levels of /sup 117/In were made in many instances. The level structure is discussed in relation to the unified model calculation and possible one-proton--two-neutron configurations.
