Simulating core excitation in breakup reactions of halo nuclei using an effective three-body force

Effective field theory analysis of the Coulomb breakup of the one-neutron halo nucleus 19C

“…This state might have a dominant single-particle structure with a 18 C core in its 0 + ground state and neutron in a d 5/2 resonance and could significantly affect the breakup cross section [30][31][32].…”

Halo EFT for 31Ne in a spherical formalism

“…The nuclear-dominated breakup on C, however, was found to be more sensitive to short-range physics. In a similar way, the effects of virtual excitation of the 11 Be core can be captured by an effective three-body force [14] or by including the excited states explicitly [15].…”

“…An estimate of the error from the nuclear contribution is beyond the scope of this work. We refer the reader to the discussion in [14,46] in the case of 11 Be. The absolute height of the peak has a large EFT uncertainty while the shape of the curve is rather robust.…”
