Abstract
Neutron absorption correction coefficients have been calculated numeri cally for annular cylindrical samples which are highly absorbing mater ials (1 < mu R < 30). The angular variation of the absorption factor d iffers from that of an equivalent full cylinder. As an example, a gain of a factor of 15 in diffracted intensity can be reached at low Bragg angles for mu R = 18 if an annular cylinder is used instead of a full cylindrical sample holder with the same amount of material.
