The dependence of the attenuation correction factor, A_{sphere}, for elastic scattering on the width of the incident beam w for scattering angles of 5, 50 and 100°. The results are presented for a spherical vanadium sample of radius r_{s} = 0.15 cm with an incident neutron wavelength of Å. For a given scattering angle, A_{sphere} is a constant for cm since the sample is then fully illuminated by the incident beam.
