Abstract
RECENT theories concerning the formation of the elements are based on neutron capture, and are subject to quantitative experimental tests through radiative capture measurements1–3. This communication reports 30 keV neutron capture measurements for the isotopes of samarium. 2–20-g samples of electromagnetically separated samarium isotopes as Sm2O3 were used with the ORNL 3-MV pulsed Van de Graaff, providing the neutrons via the lithium-7 (p,n) reaction. A Moxon-Rae counter detected the capture γ-rays as in an earlier tin isotopo measurement3.
