Collaboration:
RIKEN-RIBF123 collabolation
In this study, interaction cross sections for 58-77Ni on a carbon target at 260 MeV/nucleon have been measured at the Radioactive Isotope Beam Factory(RIBF) at RIKEN by using the BigRIPS fragment separator. The present data are the first systematic ones along the isotopic chain in Ni mass region.
In this presentation, we’ll report the matter radii derived from the experimental results using Glauber calculation and compare them with known charge radii. Also, we’ll discuss the neutron skin thickness of Ni isotopes, which is obtained by the present data combined with known charge radii.
