An investigation of the collective structures in the doubly-odd nucleus /sup 132/Pr has been undertaken with the /sup 117/Sn(/sup 19/F,4n)/sup 132/Pr reaction. Two distinct rotational structures showing both signature components have been established. One band, with no signature splitting, is built on a near-prolate ..pi..h/sub 11/2x..nu..g/sub 7/2 structure. The second band, with a small signature splitting, involves the ..pi..h/sub 11/2x..nu..h/sub 11/2 configuration with a triaxial shape. A comparison with recent results for the /sup 130/La isotone has been made. A third band structure of large signature splitting (doubly decoupled) was observed showing only one signature component. This band structure is believed to involve the ..beta..-driving ..nu..i/sub 13/2(660)(12/sup +/ orbital
