抄録	As the first step of systematic studies on neutron-rich Mg isotopes, the structure of ^<28>Mg has been investigated by β-decay spectroscopy of spin-polarized ^<28>Na at TRIUMF. Spin-parity assignments have been successfully performed for levels in ^<28>Mg by taking advantage of the anisotropic β decay. Previous assignments for three levels were reconfirmed. New assignments were performed for four levels including a newly found ^<2>+ level at 7.461 MeV. The experimental results were compared, on a level-by-level basis, with the shell-model calculation in the model space restricted to the sd shell. Overall good agreement between the experimental and theoretical results indicates dominance of the normal configurations in most of the ^<28>Mg levels. High performance of the present method promises successful application to heavier Mg isotopes to elucidate the shell evolution in the region of the N=20 island of inversion.
