Direct measurements of the masses of rubidium and cesium isotopes far from stability

Direct measurements of the masses of rubidium and cesium isotopes far from stability

The masses of neutron-deficient and neutron-rich isotopes of rubidium (/sup 74en-dash79/Rb, /sup 90en-dash99/Rb) and of cesium (/sup 117en-dash124,126/Cs, /sup 138,140en-dash147/Cs) have been determined by direct on-line mass spectrometry. The measured masses are compared to current mass predictions...

Zusammenfassung:The masses of neutron-deficient and neutron-rich isotopes of rubidium (/sup 74en-dash79/Rb, /sup 90en-dash99/Rb) and of cesium (/sup 117en-dash124,126/Cs, /sup 138,140en-dash147/Cs) have been determined by direct on-line mass spectrometry. The measured masses are compared to current mass predictions. From the trend of neutron separation energies, experimental neutron pairing energies are deduced and evidence is found for the onset of a deformation at N = 60 in the neutron-rich rubidium isotopes.
