N2 - We investigate the low-energy excitations for the impurity Anderson model under the tetragonal crystalline electric field (CEF) of which the CEF ground state is non-Kramers doublet. When the hybridization is weak, the low-energy spectrum is explained by a combination of non-Fermi-liquid (NFL) and the local-Fermi-liquid fixed point Hamiltonians which are independent of each other. The NFL part at the low-energy fixed point has the same form as that of the two-channel-Kondo model. The hybridization for a Γ7 symmetry channel diminishes in the renormalization step, and the other two channels contribute to the NFL part at the low energy fixed point. The magnetization which has -In T dependence is calculated.
