The nucleus {sup 140}Nd was investigated using {gamma}-{gamma} coincidence and angular-correlation techniques following the {epsilon}/{beta}{sup +} decay of {sup 140}Sm and {sup 140}Pr. Spins, {gamma}-decay intensities, and E2/M1 mixing ratios were extracted from the data. The 2{sub 3}{sup +} and 2{sub 4}{sup +} states were identified as possible mixed-symmetry states, based on mixing ratios obtained for observed decays to the 2{sub 1}{sup +} state. The relationship between the decay pattern of these two candidate states and underlying shell structure in this mass region is discussed.
