Shell oscillations in symmetry energy

The procedure of derivation of the symmetry energy from the shift of neutron-proton chemical potentials Δλ=λ_n-λ_p is suggested. We observe the nonmonotonic (sawtooth) shape of the β-stability line given by the asymmetry parameter as a function of mass number. The behavior of the symmetry energy coe...

description	The procedure of derivation of the symmetry energy from the shift of neutron-proton chemical potentials Δλ=λ_n-λ_p is suggested. We observe the nonmonotonic (sawtooth) shape of the β-stability line given by the asymmetry parameter as a function of mass number. The behavior of the symmetry energy coefficient b_sym (A) at fixed neutron excess D=N-Z is analyzed. We show the relation of local maxima of the β-stability line to mass numbers of the double-closed shells.
