High-spin states in /sup 103/Rh have been studied using the /sup 100/Mo(/sup 7/Li,4n..gamma..) reaction at 45 MeV. The in-beam techniques employed included relative ..gamma..-ray excitation functions, ..gamma..-..gamma.. coincidences, and ..gamma..-ray angular distribution measurements. Low-lying collective bands built on the 1g/sub 9/2/ and 2p/sub 1/2/ quasiproton states show large signature splitting. At higher excitation energies (2.346 and 3.399 MeV), two strong ..delta..I = 1 cascades are also observed with small signature splitting. These latter bands probably arise from three quasiparticle configurations. The one quasiparticle bands are interpreted within the framework of the axially symmetric rotor-plus-particle model with a variable moment of inertia, the generalized particle-asymmetric-rotor model, and the interacting boson-fermion model. High-spin features of /sup 103/Rh are compared with the predictions of the cranked shell model. All of the models indicate that /sup 103/Rh is a soft nucleus which exhibits shape coexistence.
