Evolution of high-spin states in neutron-rich Au isotopes approaching the shell closure

Y. Cho, Y. H. Kim, A. Navin +48

\textbf{Background: } The nuclear structure in the region southwest of the doubly magic Pb is important to benchmark theoretical models relevant for neutron-rich heavy elem…

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…

First Exploration of Monopole-Driven Shell Evolution above the N = 126 shell closure: new Millisecond Isomers in 213Tl and 215Tl

T. T. Yeung, A. I. Morales, J. Wu +52

Isomer spectroscopy of heavy neutron-rich nuclei beyond the N=126 closed shell has been performed for the first time at the Radioactive Isotope Beam Factory of the RIKEN Nishina Ce…

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…

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…
