Abstract

We predict the limits of existence of atomic nuclei, the proton and neutron
drip lines, from the light through medium-mass regions. Starting from a chiral
two- and three-nucleon interaction with good saturation properties, we use the
valence-space in-medium similarity renormalization group to calculate
ground-state and separation energies from helium to iron, nearly 700 isotopes
in total. We use the available experimental data to quantify the theoretical
uncertainties for our ab initio calculations towards the drip lines. Where the
drip lines are known experimentally, our predictions are consistent within the
estimated uncertainty. For the neutron-rich sodium to chromium isotopes, we
provide predictions to be tested at rare-isotope beam facilities.
