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…
