A procedure is described for preparing deuterated boric acid solutions for use in the absolute determination of the cross section for absorption of thermal neutrons and for reference standards. The suitability of these solutions as standards is discussed in terms of the purity of the reagents, the reproducibility of preparation, and the composition of the boric oxide used in the preparation.
