	Article:	RESONANCE INTEGRAL AND THERMAL CROSS-SECTION MEASUREMENTS ON SAMARIUM USING AM-BE AND PU-BE ISOTOPIC NEUTRON SOURCES. Authors: .


	Abstract: The nuclear reaction mechanism involving resonance neutrons has been studied and the resonance integral and interaction cross-section for the ¹⁵²Sm(n,γ)¹⁵³Sm reaction have been calculated after irradiation in the neutron field produced by the ²⁴¹Am- ⁹Be and ²³⁹Pu-⁹Be isotopic neutron sources. For the data and calculations to be accurate, corrections have been made all the way. These corrections include neutron self-absorbtion, gama-ray attenuation geometry of the samples, geometry of the irradiation site and non-ideality of the epithermal neutron spectrum. Keywords: resonance neutrons, resonance integral, cross section, isotopic neutron sources.
