Abstract
Levels of135Pr populated in the (p,2n) reaction were studied using methods of in-beamγ-ray and conversion electron spectroscopy. Many low-lying positive-parity states give evidence of a deformation ofβ=0.15–0.20. The same conclusion is evident from band structures built on these positive-parity states and on theh 11/2 negative-parity state. The triaxial rotor-plus-particle model reproduces quite well band structures withβ=0.20 andγ= 21°.
