Neutron absorption probability for neutrons with several wavelengths λ impinging at a distance h from the centre of a detector tube of radius r. (a) Without shadowing effects, the absorption probability drops close to the edges owing to the shorter path length in the tube [equation (26)[link]]. (b) A partially shadowed tube, equations (26)[link] and (28)[link].
