The second-phonon () wobbling band has been established in the nucleus $^{135}$Pr. Conclusive evidence for its wobbling nature comes from the , E2 character of the transitions between the new band and the previously identified transverse wobbler band () in this nucleus. Theoretical calculations in the framework of the quasiparticle triaxial rotor and triaxial projected shell models are found to be in good agreement with the experimental results.
