Abstract
Abstract
The charge exchange spin-dipole (SD) excitations of
Zr are studied using the Skyrme Hartee-Fock plus proton-neutron random phase approximation with SAMi-J interactions. The experimental value of the model-independent sum rule obtained from the SD strength distributions of
Zr(p, n)
Nb and
Zr(n, p)
Y is used to deduce the neutron skin thickness. The neutron skin thickness
of
Zr is extracted as
fm, which is similar to the results of other studies. Based on the correlation analysis of the neutron skin thickness
and the nuclear symmetry energy J as well as its slope parameter L, a constraint from the extracted
leads to the limitation of J to
MeV and L to
MeV.
