The level structure of {sup 197}Au has been studied using the (n,n{sup '}{gamma}) reaction. A germanium detector array (GEANIE) for {gamma}-ray detection and the 'white' neutron source at LANSCE/WNR were used for the measurement. The energy of the incident neutrons was determined using the time-of-flight technique. Partial {gamma}-ray cross sections were measured for a total of 90 transitions of {sup 197}Au. A total of 52 new {gamma} rays were assigned to {sup 197}Au and placed on the level scheme based on the partial {gamma}-ray excitation functions and the {gamma}-{gamma} coincidence data. The level scheme of {sup 197}Au is now more complete up to {approx}2 MeV excitation energy. The first excited states of the decoupled band built on the proton-hole h{sub 11/2} configuration were established.
