The r-process and nucleochronology

JJ Cowan, FK Thielemann, JW Truran - Physics Reports, 1991 - Elsevier
The r-process of nucleosynthesis is the process which is responsible for the synthesis of
approximately half of the nuclear species in nature that are more massive than iron. This …

Novel techniques for constraining neutron-capture rates relevant for r-process heavy-element nucleosynthesis

AC Larsen, A Spyrou, SN Liddick… - Progress in Particle and …, 2019 - Elsevier
The rapid-neutron capture process (r process) is identified as the producer of about 50% of
elements heavier than iron. This process requires an astrophysical environment with an …

Isomeric Cross-Section Ratios for Reactions Producing the Isomeric Pair

R Vandenbosch, JR Huizenga - Physical Review, 1960 - APS
Excitation functions and isomeric cross-section ratios were determined for the Au 197 (p, n)
and Au 197 (d, 2 n) reactions. Isomeric cross-section ratios were also determined for the Hg …

Novel technique for Constraining -Process (, ) Reaction Rates

A Spyrou, SN Liddick, AC Larsen, M Guttormsen… - Physical Review Letters, 2014 - APS
A novel technique has been developed, which will open exciting new opportunities for
studying the very neutron-rich nuclei involved in the r process. As a proof of principle, the γ …

A shell-model nuclear level density

H Baba - Nuclear Physics A, 1970 - Elsevier
A nuclear level-density formula was derived by introducing a stepwise single-particle level
structure. It was found to be formally identical to the well-known Fermi gas level density …

Verification of detailed balance for absorption and emission in Dy isotopes
