Abstract：
The halo or skin structure of excited states in odd nuclei near the stability line is studied in terms of the spherical nonlinear relativity mean field theory calculation, considering nucleus as a spherical core plus a valence nucleon outside it. The tail of density distributions of excited states with exotic structure are presented for medium-heavy nuclei. The ratio (R_vc) of valence nucleon rms radii to that of nuclear core are deduced. Together with the separation energy (Sn(p)), the ratio (R_vc) constitutes a correlation, in which the exotic nuclei excited states distribution presents a strap structure. It implied the effects of centrifugal barrier and the shell structure.
