Abstract

Excited states in ¹²Be and ¹⁴Be were studied by using an exotic beam of ¹⁴Be at 75 A MeV. A new excited state in ¹²Be was observed at 11.8 MeV. The angular-correlation analysis showed that the spin for the new level is tentatively assigned to be 0. According to the energy-spin systematics, the observed state may be a member of the rotational band of the ⁶He-⁶He cluster structure. Three excited states in ¹⁴Be were also found at 10.8 MeV, 11.6 MeV, and 15.5 MeV.
