Abstract

The thermal-neutron capture cross sections and resonance integrals of 138Ba(n, γ) 139Ba and 141Pr(n, γ) 142Pr were measured by activation method using an isotopic Am-Be neutron source. The estimations were with respect to that of 55Mn(n, γ) 56Mn and 197Au(n, γ) 198Au reference monitors. The measured thermal-capture cross section of 138Ba with respect to 55Mn is 0.410 ± 0.023 b and with respect to 197Au is 0.386 ± 0.019 b. The measured thermal-capture cross section of 141Pr with respect to 55Mn is 11.36 ± 1.29 b and with respect to 197Au is 10.43 ± 1.14 b. The resonance integrals for 138Ba are 0.380±0.033 b (55Mn) and 0.364±0.027 b (197Au) and for 141Pr are 21.05±2.88 b (55Mn) and 15.27±1.87 b (197Au). The comparison between the present measurements and various reported values are discussed.The cross sections corresponding to the selected isotopes are measured using an Am-Be source facility forthe first time.
