Nuclear Radii Extracted from Experimental Reaction Cross Sections

We illustrate typical experimental reaction cross sections cr n which have obtained on RIBLL at Heavy Ion Research Facility of the Institute of Modern Physics (IMP) at Lanzhou. The corresponding nuclear radii are extracted from the measured experimental an using the Glauber model. Meanwhile, theoretical nuclear radii are also calculated using Relativistic density-dependent Hartree and spherical relativistic mean-field theory with Pauli blocking. For comparison, the nuclear radii of these nuclei are a/so calculated using the empirical radius format in which the deformation has been taken into account. From the given experimental and theoretical nuclear radff, we suggest that there may exist proton halo structure in 23A1, 27p and may exist proton skin structure in 24A1. We also find that the deformation plays a great role to the nuclear radii.
