We present the recent experimental results on the 6He structure studied by the 6Li(t, 3He) 6He reaction at 336 MeV. Above the conspicuous peaks for ground and first excited states for 6He, we have observed a broad structures at MeV, and MeV. The angular distribution of this structure exhibits the dominance of a transition, indicating the existence of intruder dipole states at low excitation energies in 6He. A slight admixture of positive-parity states in this structure has been indicated as well.
