Abstract

Deep-inelastic reactions between a beam of 1360 MeV ²⁰⁸Pb ions and a thick ²³⁸U target have been used to populate the neutron-rich nucleus ²¹¹Pb. The observation of its γ decay has allowed identification of excited states up to the highest spin which can be formed from the three valence neutrons, including identification of three high-spin isomers. Level energies and transition strengths are compared to shell-model calculations with empirical interactions and predictions are made for the expected behaviour of more neutron-rich lead isotopes. The evidence for a possible increase in the neutron effective charge moving away from the N=126 shell gap is evaluated.
