High-precision ab initio radius calculations of boron isotopes

Year: 2025

Type: article

Abstract: We perform a precision study of radii in Boron isotopes for multiple realistic interactions from chiral effective field theory. We obtain predictions of radii with combined many-body and interaction uncertainty quantification from no-core shell-model calculations together with machine-learning extrapolation methods. An extension to radius differences further allows us to investigate a potential proton halo in B 8 and, moreover, provide predictions that relate directly to the isotope shift, which can be precisely measured in experiments.
