DETERMINATION OF OXYGEN IN ALUMINUM BY MEANS OF 14 MeV NEUTRONS WITH AN ACCOUNT OF FLUX ATTENUATION IN THE SAMPLE

摘要

This study concerns the determination of oxygen present at low levels in aluminum using the 1 4 MeV neutron activation technique.nThe sensitivity obtained amounted to 0. 2 mg oxygen.nVarious nuclear methods for the oxygen determination have been briefly reviewed.nThe attenuation of fast neutrons inside the aluminum samples has been calculated.
