Halo EFT calculation of charge form factor for two-neutron $^{6} He$ halo nucleus: two-body resonant P-wave interaction

S. Jesri🇮🇷 · M. Moeini Arani🇮🇷 · S. Bayegan🇮🇷

We take a new look at $^{6} He$ halo nucleus and set up a halo effective field theory at low energies to calculate the charge form factor of $^{6} He$ system with resonant P-wave interaction. P-wave Lagrangian has been introduced and the charge form factor of $^{6} He$ halo nucleus has been obtained at Leading-Order. In this study, the mean-square charge radius of $^{6} He$ nucleus relative to $^{4} He$ core and the root-mean-square (r.m.s) charge radius of $^{6} He$ nucleus have been estimated as $⟨ r_{E}^{2} ⟩ = 1.408 fm^{2}$ and $⟨ r_{E}^{2} ⟩_{^{6} H e}^{\frac{1}{2}} = 2.058 fm$ , respectively. We have compared our results with the other available theoretical and experimental data.

A study of open shell nuclei using chiral two-body interactions

We apply the Hybrid-Multi-Determinant method using the recent chiral two-body interactions of Entem-Machleidt-Nosyk (EMN) without renormalization to few nuclei up to A=48. Mostly we use the bare fifth order NN interaction N4LO-450. For

^{24} M g

and

^{48} C r

the excitation energies of the

2_{1}^{+}

states are far larger than the corresponding experimental values.
