Abstract: Relatively monochromatic soft X-rays at 4.5 m.mu. is used to induce auger electrons from the silver-halide crystal to sensitize the photosensitive grain, and the exposed crystal is developed into a fine silver grain. The pattern of the silver grains with sizes of about 0.02.mu. can be used as a photoresist with a resolution of about 0.1.mu.. The silver grains can also be used to initiate certain organic compounds for the resist, also with a resolution of the order of 0.1.mu..

Abstract: Turbo-separative methods and apparatus for separation of mixtures of gaseous materials having different molecular weights, particularly gaseous isotope mixtures such as mixtures of UF.sub.6, in which differential sedimentation velocities of the components to be separated are established in a laminar boundary layer of the gas adjacent a hydraulically smooth, porous blade surface, and in which a predetermined amount of the boundary layer flow is conducted through the porous surface to stabilize the boundary layer and to provide a higher density gas fraction. The velocity of the gas conducted through the porous blade surface should not exceed the sedimentation velocity of the gas species to be separated.

Abstract: A method of treating cancer in a human uses x-rays to disrupt a linkage in a complex of a chemotherapeutic agent and a carrier compound comprising a pre-selected element. The complex is administered to the human and then a localized region of cells which contains the cancerous cells is irradiated with line emission x-rays of an energy selected to cause emission of Auger electrons from the pre-selected element of the carrier compound to disrupt the linkage and release the chemotherapeutic agent near the cancer cells. A kit useful for the treatment comprises an x-ray tube capable of emitting monochromatic line emission x-rays and the complex compound. A transfer compound useful in the method comprises a chemotherapeutic agent linked to a carrier compound.

Abstract: This invention relates to the use of thick target materials 50 microns and thicker for an x-ray transmission tube; to possible target material compositions including various elements and their alloys, eutectic alloys, compounds, or intermetallic compounds; and applications for utilizing such thick target transmission x-ray tubes. The target comprises at lease one portion of the target with a thickness of 50 microns or greater. The target can be optionally attached to a substrate end-window essentially transparent to x-rays or be thick enough so that no such substrate is required. Applications include producing a high percentage of monochromatic line mission x-rays of said thick target for use in reduced dose medical imaging and other non-destructive testing applications.
