The energies and widths of the highly excited odd-parity resonant states of ^6Li around E_x≃18 〜27 MeV are investigated using the complex-scaled ^3He+t resonating group method (CSRGM). Our calculated results support the results of the recent combined reanalysis by Mondragon and Hernandez for elastic ^3He+ t scattering data and radiative capture data of ^3He by t, namely, that the ^<33>P and ^<33>F resonant states of ^6Li appear at E_x≃18 MeV and 25〜27 MeV, respectively. The new energy levels are smaller by about 1〜 3 MeV than those shown in the A=6 isobar diagram given by Ajzenberg-Selove. This result is consistent with the existence of a core excited ^7_ΛLi state with the [^6Li(^<33>P)&oxtimes;s_Λ] configuration which is observed in the ^7Li(K^-, π^-)^7_ΛLi reaction.
