C 106, 015501 (2022) M.Ramalho, Z.Ge, T.Eronen, D.A.Nesterenko, J.Jaatinen, A.Jokinen, A.Kankainen, J.Kostensalo, J.Kotila, M.I.Krivoruchenko, J.Suhonen, K.S.Tyrin, V.Virtanen Observation of an ultralow-Q-value electron-capture channel decaying to 75As via a high-precision mass measurement ATOMIC MASSES 75As, 76Ge; 77Se, 76Se; 94Mo, 95Mo; measured cyclotron frequency ratios using phase-imaging ion-cyclotron-resonance technique (PI-ICR) and high-precision Penning-trap mass spectrometry (PTMS) with a double Penning trap mass spectrometer (JYFLTRAP) at the IGISOL facility of the University of Jyvaskyla; deduced precise Q(β) values for decays of 75Se and 75Ge to 75As, with three ultra-low Q-value energetically valid β transitions, one of which as a possible candidate for antineutrino mass determination. Comparison with evaluated data in AME2020. RADIOACTIVITY 75Se(EC); 75Ge(β-); deduced precise Q(β) values from measurements of difference in mass excesses of 75As and 76Ge, and three ultra-low Q-value energetically valid β transitions, with one as a possible candidate for antineutrino mass determination. Comparison with evaluated data in AME2020. NUCLEAR STRUCTURE 75As; calculated levels, J, π using shell-model code NUSHELLX in a single-particle model space consisting of 1f5/2, 2p3/2, 2p1/2, and 1g9/2 neutron and proton orbitals, with jun45pn and jj44bpn interactions, and compared results with experimental data.
