Angular Dispersion Behavior in Heavy Ion Elastic Scattering
Abstract
The differential cross sections for elastic scattering products of 17F and 17O on 208Pb have been measured at Radioactive Ion Beam Line at Lanzhou (RIBLL), China. The angular dispersion plots of ln(dσ/dθ) versus θ2 are obtained from the angular distribution of the elastic scattering differential cross sections. Systematical analysis on the angular dispersion for the available experimental data indicates that there is an angular dispersion turning angle at forward angular range beyond the grazing angle. This turning angle can be clarified as nuclear rainbow in classical deflection function. And the exotic behavior of the nuclear rainbow angle offers a new probe to investigate the halo and skin phenomena.
