-The calculation method for the transitional odd-A nuclei is studied.The theo-retical calculation of the energy level structure of ~(147)pm and ~(149)EU 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. -The calculation method for the transitional odd-A nuclei is studied. Theo-retical calculation of the energy level structure of ~ (147) pm and ~ (149) EU 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.
