“…This indicates that, for the chosen astrophysical conditions, even higher mass accuracies on the order of 1 keV would be needed to fully eliminate mass-induced model uncertainties in this particular case. Such precision levels have recently been demonstrated with an MR-TOF mass spectrometer [119], encouraging a future re-measurement of the 61 Ga mass. However, other nuclear uncertainties in this region are now of higher astrophysical relevance.…”

“…According to the recent works from other research groups discussing particularly high resolving powers (see e.g. [65,66]), and to the present knowledge of the authors, this is a new record for MRTOF mass spectrometry considering the long measurement time and high number statistics of ions in the spectra. This new achievement will facilitate mass measurements of nuclear isomeric states in future, where R m ≈ 10 6 enables the identification of nuclear isomers (at FWHM level) with excitation energies of, for example, 38 keV for A/q ≈ 40, 93 keV for A/q ≈ 100, and 186 keV for A/q ≈ 200.…”
