Comparison of halo of Be-11, C-15, and C-19

摘要

We have compared the halo of Be-11, C-15, and C-19 nuclei by analyzing the one-neutron stripping reaction data on the Be target at 60-, 54-, and 57-MeV/A beam energies, respectively, within the framework of the eikonal approximation approach. The determination of effective range through the comparison of the total cross section data and prediction has revealed that the halo of C-19 is the well developed, while that of C-15 is the least and that of Be-11 lies in between these two. The longitudinal momentum distribution data also strengthen these observations.
