“…for the cesium and lanthanum isotopes. The main remaining anomaly seen at 114 Sb can be addressed by checking the binding energies of those nuclei included in this observable: 114 Sb, 112 In (previously measured with a storage ring [38]) and 110 Ag (previously measured with indirect methods [39,40]). The large uncertainties of the cesium and lanthanum d 2Z [S 2 p (N , Z )] values are caused by the mass uncertainties of the lanthanum isotopes together with the mass uncertainties of 115 Cs and 116 Cs, for which only extrapolated mass values are available in the literature [7].…”

Neutron-deficient iodine isotopes, 116 I and 114 I, were produced at relativistic energies by in-flight fragmentation at the Fragment Separator (FRS) at GSI. The FRS Ion Catcher was used to thermalize the ions and to perform highly accurate mass measurements with a Multiple-Reflection Time-of-Flight Mass-Spectrometer (MR-TOF-MS). The masses of both isotopes were measured directly for the first time. The half-life of the 114 I was measured by storing the ions in an RF quadrupole for different storage times and counting the remaining nuclei with the MR-TOF-MS. The measured half-life was used to assign the ground state to the measured 114 I ions. Predictions on the possible α-decay branch for 114 I are presented based on the reduced uncertainties obtained for the Q α-value. Systematic studies of the mass surface were performed with the newly obtained masses, showing better agreement with the expected trend in this mass region.

The fi decay Agll~Cd n~ has been investigated with a double lens spectrometer and a ~-y circular-polarization correlation setup. The shape of the 6 + -+ 6 +/~ spectrum with E 0 = 529 keV was found to be allowed, in disagreement with earlier work. The constant A of the fl-y circular-polarization correlation was measured to be A ~ 0'07 • 0.02. This implies a ratio X of Fermi to Gamow-Teller contribution +2.3 to the decay of X 1 = --0.02 ~ 0'03 or X 2 = --10.34.1. Qualitative shell model considerations favor the value X 1 . Additional information is given for the disintegration schemes of Ag ll~ and Ag n~
