Study on neutron skin of ⁹⁶Zr by using angular distribution of ¹²C+⁹⁶Zr elastic scattering

Neutron skin is one of the key parameters in nuclei. It can be used to constrain the asymmetric nuclear matter equation of state. The ⁹⁶Zr neutron skin with the angular distribution of ¹²C+⁹⁶Zr elastic scattering was studied. The best fitting optical potential parameters were figured out by comparing the experimental angular distribution of ¹²C+⁹⁶Zr elastic scattering with the results calculated with Woods-Saxon potential. A series of optical potentials were computed with double folding potential model (DFM) by using different neutron density distributions in ⁹⁶Zr. The neutron density distribution and the thickness of neutron skin in ⁹⁶Zr were studied by comparison of the two sets of optical potentials. The thickness of ⁹⁶Zr neutron skin was deduced to be 0.087 fm, and the result is in agreement with that of other work. (authors)
