The neutron halo structure of $$^{14}\hbox {B}$$, $$^{22}\hbox {N}$$, $$^{23}\hbox {O}$$ and $$^{24}\hbox {F}$$ nuclei studied via the generalised Woods–Saxon potential

Abstract

The radial wave functions of the generalised Woods–Saxon (GWS) potential within the two-body model of $$\left( \mathrm {Core}+n \right) $$ have been used to study the ground-state density distributions of protons, neutrons and matter and the associated root mean square (rms) radii of neutron-rich $$^{\mathrm {14}}\hbox {B}$$ , $$^{\mathrm {22}}\hbox {N}$$ , $$^{\mathrm {23}}\hbox {O}$$ and $$^{\mathrm {24}}\hbox {F}$$ halo nuclei. The calculated results show that the radial wave functions of the generalised Woods–Saxon potential within the two-body model succeed in reproducing neutron halo in these exotic nuclei. Elastic electron scattering form factors for these nuclei are studied by combining the charge density distributions with the plane-wave Born approximation (PWBA).
