We calculate the decay rates λ_β-c and λ_β-b of the continuum- and bound-state β^- -decays for bare ²⁰⁵Hg⁸⁰⁺ and ²⁰⁷Tl⁸¹⁺ ions. For the ratio of the decay rates R_b/c = λ_β-b/λ_β-c we obtain the values R_b/c = 0,161 and R_b/c = 0,190 for bare ²⁰⁵Hg⁸⁰⁺ and ²⁰⁷Tl⁸¹⁺ ions, respectively. The theoretical valure of the ratio R_b/c = 0,190 for the decays of ²⁰⁷Tl⁸¹⁺ agrees withing 1% of accuracy with the experimental data R_b/c = 0,188(18), obtained at GSI. The theoretical ratio R_b/c = 0,1641 for ²⁰⁵Hg⁸⁰⁺ is about 20% smaller than the experimental value R_b/c = 0,20(2), measured recently at GSI.
