Dataset: Precision mass measurement of 61Zn and updated 𝐹𝑡 value for conserved vector current tests

This is the dataset for the publication https://doi.org/10.1103/fbf3-nry6 We report a high-precision mass measurement of 61Zn, performed with the ISOLTRAP mass spectrometer at ISOLDE, CERN. Our result agrees with a recent measurement from the LEBIT Penning trap at FRIB and reduces the mass uncertainty by a factor of four. Combined with recent measurements of the mirror nuclide 61Ga performed by TITAN at TRIUMF and CSRe at HIRFL, we obtain a more accurate Q value. This new value slightly improves the determination of the corresponding Ft value in the Tz = 1/2 mirror beta decays used to test the Conserved Vector Current hypothesis in the Standard Model.
