High-spin states in the doubly odd N = 11 nucleus 132Cs have been studied. Gamma-ray linear polarization and angular correlation measurements have been performed to determine the spin and parity of the states. A rotational sequence of enhanced dipole transitions was established. This band can be described within the framework of the the tilted axis cranking (TAC) model as a band based on a weakly deformed structure in which the total angular momentum vector does not coincide with any of the principal axes of the triaxial nucleus but still is in the plane defined by the short and long axes. The theoretical description of the previously proposed chiral bands in 132Cs was extended in the framework of the core-particle coupling model (CPCM) confirming that the total angular momentum for the πh 11/2 ⊗ vh11/2 configuration is well outside any planes defined by the principal axes of the nucleus and revealing the important role of the residual proton-neutron interaction between the valence particles.
