Abstract

A variable-energy γ-source is obtained by nuclear resonance scattering of neutron-capture γ-rays through various scattering angles. Ah energy resolution of less than 10^-6 is obtained. Pb and Cd targets were employed to scatter the 7.279 and 7.632 MeV photons, respectively, of the neutron capture γ-rays of Fe. Variation of the angle of the resonantly scattered photons between 60°-150° permits an energy scan of ≈ 370 eV (for Pb) and ≈ 760 eV (for Cd) in any absorber. Thus nuclear energy levels in ¹³⁹La, Ce, Cd and ²⁰⁹Bi absorbers were photoexcited and the corresponding values of gΓ₀ were extracted from the measured absorption curve.
