Neutron Mass Absorption of the Elements

Neutron capture is a nuclear reaction in which a nucleus absorbs one or more neutrons to form a heavier nucleus. Because neutrons carry no electric charge, they enter nuclei more easily than protons. Neutron capture is the primary mechanism for nucleosynthesis of elements heavier than iron, proceeding by the rapid (r-process) or slow (s-process) pathway in stars.

Data available for 83 of 118 elements. Highest: Gadolinium (7.3). Lowest: Oxygen (0.000001).
