Relativistic mean-field description of a proton halo in the first excited(1/2)+state of17

Mirror energy difference and the structure of loosely bound proton-rich nuclei aroundA=20

“…The modified shell-model Hamiltonians can also give a good description to the binding energies of the N = 8 isotones, 18 Ne, 19 Na and 20 Mg, as shown in Table II. In these cases only the proton-proton part of the two-body interaction, V pp , contributes to the binding and excitation energies.…”

Investigations on the Nuclear Halo Structures

“…The pairing correlations are considered with the BCS approximation and Pauli blocking effect of the odd nucleon is taken into account by assuming that the odd nucleon occupies the corresponding 26 Na-26 P, 27 Mg-27 P, 28 Al-28 P, 29 Si-29 P, and 30 P-30 P. 36 and 17 F is also considered as spherical. 37 The RMF results are listed in Table 1, where B exp and B the denote the experimental and the calculated binding energies, R n , R p , R m and R LN denote the rms radii of neutron, proton, matter and the valence nucleon density distributions, ε LN is the single-particle energy of the valence nucleon, and R LN /R m is the ratio of the valence nucleon rms radius to matter rms radius. The values of B exp are taken from Ref.…”

Properties of deformed even-even nuclei nearZ=20in an improved quark mass density-dependent model

“…It is known that quantum chromodynamics (QCD) is very difficult to study in a nuclear system directly because of its nonperturbative nature, so phenomenological models reflecting the characteristics of the strong interaction are widely used in research of the properties of nuclear matter and finite nuclei. The relativistic mean field (RMF) model based on baryon and meson degrees of freedom gives a reasonable starting point for the studies of nuclear matter as well as the physical properties of finite nuclei [1][2][3][4][5][6]. Meanwhile, many effective models based on quark and meson degrees of freedom have also been proposed.…”
