Abstract: (APS)
Using high-precision Penning trap mass spectrometry at the Low Energy Beam and Ion Trap facility at the National Superconducting Cyclotron Laboratory we have measured the Q values of the fourth-order forbidden β decay and electron capture of V50 and the double electron capture Q value of Cr50 with the results Qβ(V50)=1038.1(1) keV, QEC(V50)=2208.7(1) keV, and Q2EC(Cr50)=1170.5(1) keV. In addition, we have measured the atomic masses of Ti46,47,49,50,V50,51, and Cr50,52–54, reducing uncertainties by factors of up to three compared with the most recent atomic mass evaluation (Ame2016) [Chin. Phys. C 41, 030003 (2017)1674-113710.1088/1674-1137/41/3/030003]. Our results are in good agreement with Ame2016 for Ti46,47,49,50 and Cr50,54 and show deviations of up to ∼1keV(2.5σ) for V50,51 and Cr50,54.References(0)
