New Ground State in La Removes Two-Neutron-Separation-Energy Anomaly in Lanthanum Isotopes

S. Kimura, M. Wada, H. Haba +9

Nuclear mass is a key indicator of how the nuclear shell structure evolves. The recent mass measurement study of neutron-rich lanthanum isotopes [A. Jaries, ., Phys. Rev. Le…

Precision mass measurements around Mo rule out ZrNb cycle formation in the rapid proton-capture process at type I X-ray bursts

S. Kimura, M. Wada, C. Y. Fu +27

The rapid proton-capture (-) process is one of the primary, explosive thermonuclear burning processes that drive type I X-ray bursts. A possible termination of the -process…

Direct observation of and decay from a high-spin long-lived isomer in Ta

J. L. Chen, H. Watanabe, P. M. Walker +20

Ta (, ) is located in the neutron-rich region where a prolate-to-oblate shape transition via triaxial softness is predicted to take place. A pr…

First direct observation of isomeric decay in neutron-rich odd-odd Ta

Y. X. Watanabe, P. M. Walker, Y. Hirayama +19

De-excitation rays associated with an isomeric state of Ta were investigated. The isomers were produced in multinucleon transfer reactions between a Xe beam and…

Alpha-decay-correlated mass measurement of 206,207Ra using an -TOF detector equipped MRTOF-MS system

T. Niwase, M. Wada, P Schury +25

The atomic masses of the isotopes Ra have been measured via decay-correlated mass spectroscopy using a multi-reflection time-of-flight mass spectrograph equipped with a…

First high-precision direct determination of the atomic mass of a superheavy nuclide

P. Schury, T. Niwase, M. Wada +25

We present the first direct measurement of the atomic mass of a superheavy nuclide. Atoms of Db (=105) were produced online at the RIKEN Nishina Center for Accelerator-B…
