Description
An isomeric 0+ state in 12Be was found at Ex=2.24 MeV. The isomer was identified by measuring coincident two γ-rays from in-flight 12Be nuclei, 12mBe→12Be* (2+1)→12Beg.s., produced by the projectile fragmentation of 18O at 100 A MeV on a beryllium target. Its spin was determined to be 0+ by the angular correlation of the two γ-rays. The low excitation energy of the 0+ state is a strong evidence of the break of the N=8 shell closure in the 12Be nucleus
