The QEC value of the superallowed β+ emitter Sc42 has been measured with the JYFLTRAP Penning-trap mass spectrometer at the University of Jyväskylä to be 6426.350(53) keV. This result is at least a factor of four more precise than all previous measurements, which were also inconsistent with one another. As a byproduct we determine the excitation energy of the 7+ isomeric state in Sc42 to be 616.762(46) keV, which deviates by 8σ from the previous measurement.

High-precision mass measurements for the isobaric multiplet mass equation at A = 52

Nesterenko, Dmitrii; Kankainen, Anu; Canete, Laetitia; Block, M.; Cox, Daniel; Eronen, Tommi; Fahlander, C.; Forsberg, U.; Gerl, J.; Golubev, P.; Hakala, Jani; Jokinen, Ari; Kolhinen, Veli; Koponen, Jukka; Lalović, N.; Lorenz, Ch.; Moore, Iain; Papadakis, Philippos; Reinikainen, Juuso; Rinta-Antila, Sami; Rudolph, D.; Sarmiento, L. G.; Voss, Annika; Äystö, Juha (IOP Publishing Ltd, 2017)

Masses of 52Co, 52Com, 52Fe, 52Fem, and 52Mn have been measured with the JYFLTRAP double Penning trap mass spectrometer. The isobaric multiplet mass equation for the T = 2 quintet at A = 52 has been studied employing the ...
High-precision mass measurements of 25Al and 30P at JYFLTRAP
