might work as a better link
if it doesn’t you can search for Electron Capture at the site

it gets modified when I post it, so I’m taking out the http:// part in order to be able to paste it in.
http://en.wikipedia.org/wiki/Neutron_capture — “Since neutrons have no electric charge they can enter a nucleus more easily than positively charged protons, which are repelled electrostatically. Neutron capture plays an important role in the cosmic nucleosynthesis of heavy elements. In stars it can proceed in two ways - as a rapid process (an r-process) or a slow process (an s-process). Nuclei of masses greater than 56 cannot be formed by thermonuclear reactions (i.e. by nuclear fusion), but can be formed by neutron capture.”
