High-Lying 6Li Levels at Excitation Energy of around 21 MeV

The 3 cluster structure in 6 Li was investigated by the 3 H($\alpha$, 3 H 3 He)n kinematically complete experiment at the incident energy $E_{\alpha} = 67.2$ MeV. We have observed two resonances at $E_{x}^{*} = 21.30$ and 21.90 MeV, which are consistent with the results of 3 He( 3 H, $\gamma$) 6 Li analysis in the Ajzenberg-Selove compilation. Our data are compared with the previous experimental data and the RGM and CSRGM calculations.
