WatanabeMass measurements of isotopes around the A=184 region near stability were performed at the KEK Isotope Separation System within the RIKEN Nishina Center, Japan. The isotopes were produced via multi-nucleon transfer reactions with a 136Xe beam of 7.2 MeV/u impinging on a natural tungsten target. We report the first direct mass measurement of 184Ta, showing a 62(27) keV deviation compared to previous indirect measurements.
