Abstract

The Q value of the double-electron capture in 108Cd has been determined to be (272.04 ± 0.55) keV in a direct measurement with the double-Penning trap mass spectrometer TRIGA-TRAP. Based on this result a resonant enhancement of the decay rate of 108Cd is excluded. We have confirmed the double-β transition Q values of 106Cd and 110Pd recently measured with the Penning-trap mass spectrometers SHIPTRAP and ISOLTRAP, respectively. Furthermore, the atomic masses of the involved nuclides (106,108,110Cd, 106 ,108,110Pd) have been directly linked to the atomic mass standard.
