Mass measurements of relativistic exotic nuclei

Short-lived exotic nuclei have been produced by projectile fragmentation of relativistic bismuth projectiles. The masses of more than hundred neutron- deficient nuclei, whose mass was unknown before,have been determined by usi ng the Schottky Mass Spectrometry. This paper concentrates on nuclear-struc ture properties, which can be derived from ground-state masses such as shel l effects, proton-separation energies and proton-pairing energies.
