Neutron Capture Cross Sections of Tantalum from 2.6 to 1900 keV

Neutron capture by a tantalum sample was measured at the Oak Ridge Electron Linear Accelerator pulsed neutron time-of-flight facility on a 40-m flight path. Average cross sections for ¹⁸¹Ta(n,γ) in the energy range from 2.6 to 1900 keV were derived. The partially resolved region from 2620 to 4000 eV was fitted in terms of resonance parameters by least-squares adjustment.
