Microscopic Study of Charge Properties in Halo Nuclei
arXiv:2607.11156 · doi:10.1103/vnmp-n6vf
The paper uses relativistic continuum Hartree‑Bogoliubov theory with electromagnetic corrections to study charge distributions in neutron‑halo nuclei of neon and phosphorus isotopes, identifying characteristic extended charge tails and distinctive low‑momentum form‑factor signatures.
Abstract
Employing the relativistic continuum Hartree-Bogoliubov (RCHB) theory with intrinsic electromagnetic structure corrections, this work primarily investigates the charge properties of halo nuclei along the Ne and P isotopic chains. Our results characterize halo nuclei by an extended tail in the charge density and distinct signatures in the charge form factors at low momentum transfer. Moreover, the higher-order radial moments of nuclear charge density, particularly the eighth moment, exhibit pronounced oscillations, serving as a key indicator of the neutron halo structure. These special features in nuclear charge distributions will serve as key references for identifying halo nuclei.
