Abstract | Measurements of reaction cross-sections (sigma(R)'s) for some proton-rich nuclei (N = 11 15 isotones) oil carbon target at intermediate energies have been performed on RIBLL of HIRFL. A larger enhancement of the sigma(R) for P-27 has been observed than for its neighboring nuclei. A large difference between the proton and neutron density distributions (proton halo) is necessary to explain the enhanced cross-section for P-27 within the framework of the Glauber model. Density distributions with HO-type core plus Yukawa-square tail and rms radii for P-27 have been deduced from the measured sigma(R) data for the first time, which conform the, long tail in its densities as predicted by RMF calculations. |
