Various aspects of X-ray lasers are discussed in approximately 122 citations. Included are laser plasmas and outputs, plasma radiation, far ultraviolet radiation, gamma rays, optical pumping, optical resonators, and electron transitions. Laser applications, laser materials, and laser fusion are also included.
Various aspects of neodymium yag lasers are discussed in approximately 267 citations. Laser materials and outputs, laser mode locking; crystal, fiber, and nonlinear optics, optical pumping communications, energy conversion efficiency, and laser applications are covered. Pulsed, continuous wave, solid state, Q switched, infrared, and dye lasers are included.
These citations from the international literature cover various aspects of remotely piloted vehicles. Included are articles concerning aircraft design, flight tests, aircraft control, cost effectiveness, automatic flight control, automatic pilots, and data links. Civil aviation applications are included, although military uses of remotely piloted vehicles are stressed. This updated bibliography contains 224 citations, 43 of which are new additions to the previous edition.
These citations from the international literature concern the storage of hydrogen in various metal hydrides. Binary and intermetallic hydrides are considered. Specific alloys discussed are iron titanium, lanthanium nickel, magnesium copper and magnesium nickel among others.
Approximately 213 citations from the international literature which concern the development of the optical data storage system technology are presented. Topics covered include holographic computer storage devices, crystal, magneto, and electro-optics, imaging techniques, in addition to optical data processing and storage.
Entries for 3900 patents and patent applications citations for the period May 1980 through December 1980 are listed. Indexes for subject, invention, source, number, and accession number are included.
Rate constants are reported for the reactions of Cl(+) and HCl(+) with H2 over the temperature range 150-400 K. The Cl(+) reaction has a positive temperature dependence that follows the Arrhenius form k1 = A exp(-169/T). The reaction of HCl(+) has a negative temperature dependence that follows the form k2 = AT to the -0.6 power. The implication of these results for interstellar chemistry is commented on. Schematic potential surfaces for the reactions are suggested.
