Three-body coupled-channel calculations were made of the fusion rate of the muonic molecule d^3Heμ and the particle-decay rates (λ_p) of d^3Heμ and d^4Heμ. It was found that the fusion rate of d^3Heμ is much smaller than the particle-decay rate and radiative-decay rate (λ_γ); unfortunately, d^3Heμ decays into (Heμ)_<1s>-d channel before the fusion. It was also found thatλ_p≃3λ_γ in d^3Heμ, whereasλ_p≃λ_γ in d^4Heμ. As a result, we can explain the strong isotope dependence in the observed X-ray strength between d^3Heμ and d^4H3μ. Fusion rate of d^3Heμ is very much smaller than the rate of the particle decay and radiative decay; unfortunately, muon catalyzed d-^3He fusion is not possible at all. The huge ^3He source in the moon surface should be utilized with magnetic or inertia confinement systems.
