Abstract

Neutron capture cross section (σ₀) and resonance integral (I₀) of the reaction ¹⁸⁶W(n,γ)¹⁸⁷W were measured experimentally using the research reactor (ETRR-2) and an Am–Be neutron source, also calculated using TALYS-1.6 code. The present results of σ₀ are (39.08±2.6, 38.75±0.98 and 38.33 barn) and I₀ are (418.5±74, 439.3±36 and 445.5 barn) by using the reactor, neutron source and TALYS-1.6, respectively. The present results are in acceptable agreement with most of the previous experimental and evaluated data as well as the theoretical calculations.

Keywords: Neutron capture cross section; resonance integral; neutron source; research reactor; TALYS-1.6
