-The calculation method for the transitional odd-A nuclei is studied.The theo-retical calculation of the energy level structure ofpm andEU is performed bycoupling the 1+3 quasiparticles to the anharmonic vibration of the core.Aparticle-number-conservation treatment is made by means of the projection method.The effects of the particle-number projection,the three-d-boson excitation and residualinteraction on the lower excited states are discussed.
