摘要：

The low spin structure of Ba-130 was investigated via the emitted gamma-radiation following the beta-decay of La-130. New ''K = 0''- and ''K = 4''-bands were identified. A comparison with the 0(6) symmetry of the IBM is shown. A discussion of the low lying levels of the 0(6) symmetry in terms of multiple quadrupole ''phonon'' excitations built on the ground state is given.
