High spin states have been studied in133La via the122Sn (15N, 4ny) fusion evaporation reaction. Bands build on low lying h11/2,g7/2 and d5/2 proton states have been identified. At higher spin a h11/2 neutron alignment is observed. The softness with respect to the triaxial deformation makes the nuclear shape sensitive to the quasiparticle configurations and coexistence between states with y ≈ + 30°, y ≈ - 30° and y ≦ - 60° was found. The results have been interpreted using total routhian surface (TRS) model calculations.
