High accuracy energy-level calculations of the rotational-vibrational weakly bound states of ddμ and dtμ mesic molecules

Abstract Calculations are performed of the nonrelativistic energies E JV of rotational-vibrational weakly bound states J = ν = 1 of ddμ and dtμ mesic molecules: E 11 ( dd μ) = − 1.956 eV and E 11 ( dt μ) = − 0.656 eV with an accuracy of 0.001 eV. With the relativistic effects and nuclear finite size corrections taken into account the result is: E 11 ( dd μ) = − 1.946 eV and E 11 ( dt μ) = − 0.634 eV .
