Double resonant enhancement in the neutrinoless double-electron capture of ¹⁹⁰Pt

ATOMIC MASSES ^190,194Pt, ^186,190Os; measured ratio of the cyclotron frequencies using LEBIT Penning trap mass spectrometer at NSCL-MSU; deduced precise Q value for ϵϵ decay of ¹⁹⁰Pt. Comparison with AME-2012 evaluation.

RADIOACTIVITY ¹⁹⁰Pt(2EC); measured precise Q value from mass measurements of ¹⁹⁰Pt and ¹⁹⁰Os; deduced parameters of the resonantly enhanced 0νϵϵ decays to excited states in ¹⁹⁰Os. Comparison of Q value with AME-2012 evaluation.
