Abstract: A glow discharge tube for atomic light-absorption analysis in which a hollow cathode for producing atomic light-absorption lines comprises a molded article of fine powder containing at least one metal element which produces the atomic lightabsorption lines, the article being molded without heating it whereby the dislocation of atomic distance remains in the crystalline lattice to improve the sputtering rate of the metal atom so that the density of metal atoms in the hollow of the hollow cathode is increased to enhance the light intensity of the atomic light-absorption lines.

Abstract: A hollow cathode lamp of the type used as a source of spectral radiation characteristic of the materials within the hollow cathode. More particularly, the cathode is comprised of a body of material of which a characteristic radiation is desired having hollow within a front surface and an electrical conductive sleeve member surrounding said cathode body and extending beyond the front surface of the cathode body and electrically interconnected with the cathode lead-in.
