In the treatment of the vibrational mode of even-even nuclei, Dynamical Nuclear Field Theory (DNFT) in the Tamm-Dancoff (TD) representation exhibited the defect to include unlinked cluster terms. We aim to remove this deficiency. In lowest order of the repetitive actions of the particle-boson couplings, we generate ∣0)_B ⊗ ∣n TD fermion pairs> states out of∣0>_F ⊗ ∣n bosons) states. We impose the lowest order self-consistency. The modified DNFT gives the normal-ordered linked-cluster expansion, in complete equivalence with the boson expansion theory (BET), of Kishimoto, Tamura and Sakamoto.
