This process produces stable isotopes by moving along the valley of beta-decay stable isobars in the chart of isotopes. The s-process produces approximately half of the isotopes of the elements heavier than iron, and therefore plays an important role in the galactic chemical evolution. The more rapid r-process differs from the s-process by its faster rate of neutron capture of more than one neutron before beta-decay takes place.
