High-spin states have been studied in neutron-deficient ${}_{}{}^{132}{}_{}{}^{}\mathrm{Nd}$, produced in the ${}_{}{}^{105}{}_{}{}^{}\mathrm{Pd}({}_{}{}^{35}{}_{}{}^{}\mathrm{Cl}, \alpha p3n\gamma )$ reaction, using the Gammasphere $\gamma$-ray spectrometer in conjunction with the Microball charged-particle detector array, Three new, weakly populated rotational bands have been found, which are believed to be associated with a superdeformed (second minimum) prolate shape. Comparison of the properties of these bands with Woods-Saxon cranking calculations suggests that they are built upon negative-parity neutron configurations that involve only one intruder orbital ($\nu i_{\frac{13}{2}}$) from the $N=6\mathrm{}$ shell. One of the bands has been linked into the normally deformed states allowing an estimation of the spin, parity, and excitation energy of the band.
