Abstract The density distributions of the last neutron in 209Pb wereinvestigated by analysis of the 208Pb(d,p)209Pb transfer reactions at 8 MeV. The results show that the last neutron in the 2d5/2,3s1/2,1g7/2 and 2d3/2 states is present with appreciable probability at distances much larger than the core radius. Therefore, these states should be the neutron halo or skin states. Moreover, the density distributions extracted illustrate that there is intrinsic relationship between the node number of state and the halo formation.
