Experimental cross section for the ¹⁵²Sm(n, γ)¹⁵³Sm reaction at 0.0334 eV

Abstract

The neutron capture cross section for the 152 Sm( , ) 153 Sm reaction at an energy of 0.0334 eV was measured for the first time using monochromatic neutrons of a powder diffractometer at the TRIGA Mark II nuclear reactor at Dhaka, Bangladesh. The 197 Au( , ) 198 Au reaction was used to monitor the neutron beam intensity. The radioactivity of the products was determined via high resolution -ray spectrometry. The obtained cross section value is 184 ± 22 b, which is consistent with both the ENDF/B-VII and TENDL-2012 data libraries. The measured value at 0.0334 eV and the previous data at 0.0536 eV confirm the reliability of the data in the above libraries.

Measurement of cross section of the 98Mo(n, γ)99Mo reaction using monochromatic thermal neutrons

“…The details of the arrangement for the monochromatization of reactor neutrons were reported elsewhere [12,13].…”

“…The method of measurement at those two energies has been well established in our laboratory and good results were obtained for several reactions [10][11][12][13][14]. Thereafter, the values measured at those two energies should be extrapolated to obtain values at 0.0253 eV.…”

Activation cross section measurement of alpha-particle induced reactions on natural neodymium

“…153 Sm and 145 Sm are generally obtained via neutron capture reactions on enriched 152 Sm and 144 Sm, respectively, in nuclear reactors (International Atomic Energy Agency, 2011;Uddin et al, 2014Uddin et al, , 2008. However, the specific activity of the 153 Sm produced in reactors by the neutron capture reaction is rather low (Qaim et al, 2007;Tárkányi et al, 2014).…”
