Neutron-capture elements in the early galaxy
C Sneden, JJ Cowan, R Gallino - Annu. Rev. Astron. Astrophys., 2008 - annualreviews.org
The content of neutron-capture (trans-iron-peak) elements in the low-metallicity Galactic
halo varies widely from star to star. The differences are both in bulk amount of the neutron …
