Abstract

The range corrections to the universal properties and structure of two-neutron halo nuclei are investigated within an effective quantum mechanics framework. Treating the nucleus as an effective three-body system, we make a systematic improvement upon previous calculations by calculating the linear range corrections at next-to-leading order. Since the effective ranges for the neutron–core interactions are not known, we estimate the effective range to be set by the inverse of the pion mass. We investigate the possibility of excited Efimov states in two-neutron halo nuclei and calculate their mean square radii to next-to-leading order. We find that the effective range corrections are generally small and the leading order predictions are very robust.

Core momentum distribution in two-neutron halo nuclei
2016, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The core momentum distribution of a weakly-bound neutron–neutron–core exotic nucleus is computed within a renormalized zero-range three-body model, with interactions in the s-wave channel. The halo wave-function in momentum space is obtained by using as inputs the two-body scattering lengths and the two-neutron separation energy. The core momentum densities are computed for ¹¹Li, ¹⁴Be ²⁰C and ²²C. The model describes the experimental data for ¹¹Li, ¹⁴Be and to some extent ²⁰C. The recoil momentum distribution of the ²⁰C from the breakup of ²²C nucleus is computed for different two-neutron separation energies, and from the comparison with recent experimental data the two-neutron separation energy is estimated in the range $100 ≲ S_{2 n} ≲ 400 keV$ . The recoil momentum distribution depends weakly on the neutron-²⁰C scattering length, while the matter radius is strongly sensitive to it. The expected universality of the momentum distribution width is verified by also considering excited states for the system.
Halo effective field theory constrains the solar 7Be + p → 8B + γ rate
2015, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
We report an improved low-energy extrapolation of the cross section for the process ${}^{7}{Be} (p, γ) {}^{8}B$ , which determines the ⁸B neutrino flux from the Sun. Our extrapolant is derived from Halo Effective Field Theory (EFT) at next-to-leading order. We apply Bayesian methods to determine the EFT parameters and the low-energy S-factor, using measured cross sections and scattering lengths as inputs. Asymptotic normalization coefficients of ⁸B are tightly constrained by existing radiative capture data, and contributions to the cross section beyond external direct capture are detected in the data at $E < 0.5 MeV$ . Most importantly, the S-factor at zero energy is constrained to be $S (0) = 21.3 \pm 0.7 eV b$ , which is an uncertainty smaller by a factor of two than previously recommended. That recommendation was based on the full range for $S (0)$ obtained among a discrete set of models judged to be reasonable. In contrast, Halo EFT subsumes all models into a controlled low-energy approximant, where they are characterized by nine parameters at next-to-leading order. These are fit to data, and marginalized over via Monte Carlo integration to produce the improved prediction for $S (E)$ .
