The paper reports a significant advance in the determination of the limit of how many neutrons a given number of protons can bind to (known as the neutron drip line), with the discovery of two new neutron-rich isotopes predicted to be drip line nuclei. Nuclei at the drip line gain stability from an unpaired proton, which narrows the shell gaps and provides the opportunity to bind many more neutrons.
