Abstract

In the present work, we use a finite range effective interaction to calculate the neutron skin thickness in 48^{48}Ca and correlate these quantities with the parameters of nuclear symmetry energy. Available experimental data on the neutron skin thickness in 48^{48}Ca are used to deduce information on the density slope parameter and the curvature symmetry parameter of the nuclear symmetry energy at saturation and at subsaturation densities. We obtained the constraints such as 54.5L(ρ0)97.554.5\leq L(\rho_0) \leq 97.5 MeV and 47.3L(ρc)57.147.3\leq L(\rho_c) \leq 57.1 MeV for the density slope parameter. The constraints on the curvature symmetry energy parameter are obtained as 170.7Ksym(ρ0)43.4-170.7\leq K_{sym}(\rho_0) \leq -43.4 MeV and 80.8Ksym(ρc)23.8-80.8\leq K_{sym}(\rho_c) \leq 23.8 MeV. A linear relation between the neutron skin thickness in 48^{48}Ca and in 2088^{2088}Pb is obtained.
