Excited states in $$^{32}$$Mg have been observed from a $$beta$$-decay experiment of $$^{32}$$Na which was performed at National Superconducting Cyclotron Laboratory in Michigan State University. The 2.1 MeV state proposed previously was denied because the corresponding $$gamma$$ ray is found to be located elsewhere. New level scheme is proposed and compared with the Monte Carlo shell model by JAEA. The ground state of $$^{32}$$Na appears to be a negative parity states from the decay pattern and the calculation. We suggested that the configuration of the states which are strongly populated via the $$beta$$ decay is 3p-3h, since the ground state of the parent nucleus is most likely 2p-3h character.
