Faddeev calculation of thedtμ−mesic molecule

An improved version of our previously developed method [C.-Y. Hu, A. A. Kvitsinsky, and S. P. Merkuriev, Phys. Rev. A 45, 2723 (1992)] of solving the Faddeev equations in the total angular momentum representation is applied to calculate the dt${\mathrm{\mu }}^{\mathrm{-}}$ ground and excited S-state energies with an accuracy of ${10}^{\mathrm{-}6}$.
