    Abstract

    The differential cross-sections for elastic scattering of 17F and 17O on 208Pb have been measured at Radioactive Ion Beam Line at Lanzhou (RIBLL). The variation of the logarithms of differential cross-sections with the square of scattering angles, viz. angular dispersion plot, shows clearly that there exists a turning point in the range of small scattering angles (6°-20°) for 17F due to its exotic structure, while no turning point was observed for 17O. The experimental results have been compared with previous data of other groups. Systematical analysis on the available data seems to conclude that there is an exotic behavior of elastic scattering angular dispersion of weakly bound nuclei with halo or skin structure as compared with that of the stable nuclei. Therefore the fact that the turning point of the elastic scattering angular dispersion plot appears at small angle for weakly bound nuclei can be used as a new probe to investigate the halo and skin phenomenon.
