Limits of nuclear stability (drip lines)

Determine the limits of the existence of bound nuclei across the nuclear chart by ascertaining the locations of the neutron and proton drip lines, identified where one- and two-nucleon separation energies become non-positive.

Background

The boundaries of the nuclear landscape—where nuclei cease to be bound—are central open questions in nuclear science with implications for nucleosynthesis and fundamental interactions.

The authors combine MISR and the Duflo–Zuker model via Bayesian ARD regression to estimate separation energies and bound-state probabilities, acknowledging that determining these limits remains an open problem motivating their ensemble approach.
