Highly excited odd-parity resonant states of 6Li around Ex≅18-27 mev with the complex-scaled 3He+t resonating group method

The energies and widths of the highly excited odd-parity resonant states of 6Li around Ex≅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 33P and 33F resonant states of 6Li appear at Ex≅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 Λ7Li state with the [6Li(33P)XsΛ] configuration which is observed in the 7Li(K-, π-)Λ7Li reaction. (author)
