The state-to-state dielectronic recombination (DR) rate coefficients of Lithium-like Hf, Ta, W and Re via Δn=0 and 1 resonances have been calculated at the energy range of 0.1～9.0 keV. The calculation based on relativistic multi-configuration Hartree-Fock (HFR) code which includes mass-velocity correction, spin-orbit coupling, Darwin term, and roughly Breit and retardation energies. The variation of state-to-state DR rate coefficients with the electronic temperature, DR type, and the principal quantum number of intermediate resonance states is discussed. The results show that some state-to-state DR rate coefficients are very small, therefore the total DR rate coefficients for some states, such as W71+(1s22s3d)0 and (1s22s3p)0 are several orders smaller than others, so it would be possible that the particle population of highly charged ions is reversed between some states by DR mechanism.
