Thermal-neutron-capture γ rays from the reaction Pb207(n,γ)Pb208

The thermal-neutron-capture γ-ray spectra from natural Pb and enriched Pb207 have been studied with a 20-cm3 Ge(Li) detector. A careful comparison of these spectra reveals the existence of two weak γ-ray cascades (intensity ≅ 10-3 times the intensity of the primary transition to the Pb208 ground sta...
