Abstract

We report on the first direct mass measurements of the 118,119Cd and 117–119In isotopes performed at the Ion
Guide Isotope Separator On-Line facility using the JYFLTRAP double Penning trap mass spectrometer. The masses of 117In and 118Cd isotopes are in agreement with the literature, while 118,119In and 119Cd differ from literature by 49, 13, and 85 keV (6.1, 1.9, and 2.1 standard deviations), respectively. The excitation energy of the 118In first isomeric state, Ex = 40.3(25) keV, was determined for the first time. The updated mass values removed the fluctuations observed in the two-neutron separation energies and led to a smoother linear decrease of both isotopic chains. The log(f t) value for the 118Cd decay was also found to increase from 3.93(6) to 4.089(8). The reported results indicate an absence of significant structural changes around N = 70.
