"In neutrino physics, a variety of experiments aim for the determination of the neutrino mass by means of the beta-decay and electron-capture spectra, while a detection of the neutrinoless double-electron capture would reveal the Majorana nature of neutrinos. However, a lack of knowledge on the total decay energy (Q-value) of these processes constrains present neutrino experiments.\r\n\r\nTo this end, high-precision measurements of the Q-values are obligatory. In order to find suitable nuclides for neutrinoless double-electron capture experiments, a determination of the Q-values by direct Penning-trap mass-ratio measurements on 106Pd/102Ru, 106Cd/106Pd, 144Sm/144Nd and 156Dy/156Gd with a relative precision of a few 10E−9 were performed for the first time at SHIPTRAP using the Time-of-Flight Ion-Cyclotron-Resonance (ToF-ICR) detection technique and the multiresonance phenomenon in 156Dy was discovered.\r\n\r\nA novel Phase Imaging Ion-Cyclotron-Resonance detection technique was developed being substantially faster and providing ca. 40-fold gain in resolving power in comparison with the presently used ToF-ICR technique.\r\n\r\nThe novel Penning-trap mass spectrometer PENTATRAP aims for direct mass-ratio measurements with a relative precision better than 10E−11, which is required for the beta-decay and electron-capture experiments. In this context, the PENTATRAP Control System was developed in order to maximize the efficiency of the measurement process."^^ . "2014" . . . . . . . "Mikhail Leonidovich"^^ . "Goncharov"^^ .
