The structure of the energy levels of light nuclei has still many states unknown. In particular in the triplet 6Li, 6He, and 6Be. There are several excited states identiﬁed in the 6Li and 6He but only a few states in the isobar 6Be. In addition to the interest in nuclear structure of these states, the importance of the excited states in the 6Be below and above the 3He−3He threshold at 11.48MeV resides mainly in the astrophysics. The possible existence of resonances near to this threshold could have strong implications in the p-p burning captures in the p-p chain. The idea here was to use a reaction 3He(7Be, α)6Be to populate the 6Be levels. The experiment was performed at CRIB-RIKEN using a pure 7Be beam and a 3He gas target. The 7Be beam of intensity of about 3− 5x105pps and Elab = 53.4MeV was produced by the primary reaction 7Li(p, n)7Be using the criogenic H2 target at CRIB. In this work we analize data from this 3He(7Be, α)6Be reaction and show results of the searching for resonances in 6Be.
