The astrophysical rapid neutron capture process or 'r process' of nucleosynthesis is believed
to be responsible for the production of approximately half the heavy element abundances …

The rapid neutron capture process (r process) is believed to be responsible for about half of
the production of the elements heavier than iron and contributes to abundances of some …

Background: r-process nucleosynthesis models rely, by necessity, on nuclear structure
models for input. Particularly important are β-decay half-lives of neutron-rich nuclei. At …

In-flight separators have played a significant role in the physics of exotic nuclei. In the last
decade, in particular, this field has expanded rapidly with the advent of the new-generation …

The β-delayed neutron emission probabilities of neutron rich Hg and Tl nuclei have been
measured together with β-decay half-lives for 20 isotopes of Au, Hg, Tl, Pb, and Bi in the …

Current models for the r process are summarized with an emphasis on the key constraints
from both nuclear physics measurements and astronomical observations. In particular, we …

This Letter reports on a systematic study of β-decay half-lives of neutron-rich nuclei around
doubly magic Pb 208. The lifetimes of the 126-neutron shell isotone Pt 204 and the …

A Laser Ion Source and Trap (LIST) for a thick-target, isotope-separation on-line facility has
been implemented at CERN ISOLDE for the production of pure, laser-ionized, radioactive …

Polonium isotopes having two protons above the shell closure at Z= 82 show a wide variety
of low-lying, high-spin isomeric states across the whole chain. The structure of neutron …

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 …
