New Ground State in $^{149}$ 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, $e t a l$ ., Phys. Rev. Le…

Precision mass measurements around $^{84}$ 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 ( $r p$ -) process is one of the primary, explosive thermonuclear burning processes that drive type I X-ray bursts. A possible termination of the $r p$ -process…

Direct observation of $I^^{2}$ and $I^^{3}$ decay from a high-spin long-lived isomer in $^{187}$ Ta

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

$^{187}$ Ta ( $Z = 73$ , $N = 114$ ) is located in the neutron-rich $A \approx 190$ region where a prolate-to-oblate shape transition via triaxial softness is predicted to take place. A pr…
