291. Open quantum system behavior of a near threshold resonance in 11B

Oral contribution

A narrow near-threshold proton-emitting resonance (Ex=11.4 MeV,Jπ= 1/2+ and Γp= 4.4 keV) was directly observed in $^{11}$B via proton resonance scattering. This resonance was previously observed in the β-delayed proton emission of the neutron halo nucleus $^{11}$Be [1].The good agreement between both experimental results serves as a ground to confirm the existence of such exotic decay and the...

227. Systematics of reaction cross sections and geometrical parameters from double folding and single folding optical potentials

Oral contribution

At the moment a hot topic of research is the description of the residual-nucleus-target part of knockout reactions from exotic projectiles with large differences in the valence neutron-proton separation energies. Comparing a large set of theoretical and experimental reaction cross-sections, for some light projectiles on a 9Be, we provide a quantitative assessment of the description of the...

280. Isospin dependence of NN correlations, quenching of spectroscopic factors, and effects on other nuclear structure observables

Oral contribution

Although the atomic nucleus consists of strongly interacting nucleons, it is noteworthy that for such strongly interacting quantum system the independent-particle model is proven to be a valid approximation and has provided a basic framework to explain many properties of nuclei. However, correlations between the nucleons, both of short- and long-range nature, modify the mean-field...

282. Global optical potential from chiral EFT and applications to charge-exchange reactions

Taylor Ray Whitehead (MSU)

27/06/2022, 16:00

Oral contribution

The study of exotic nuclei will offer direct insights into fundamental questions in physics, such as the nucleosynthesis of heavy elements and the structure of neutron stars. As rare isotope beam facilities around the world extend their reach to increasingly exotic regions of the nuclear chart, reaction theory models with robust error estimates will be crucial to drive scientific discovery.
