Abstract: Isotope enrichment by laser activation wherein a multi-isotopic element Q, like Uranium, Silicon, Carbon is incorporated into gaseous QFn, QF6, QF4, QOmFn, etc and diluted in gas G like He, N2, Ar, Xe, SF6 or other inert gas; and wherein that mixture is cooled by adiabatic expansion or other means encouraging formation of dimers QF6:G in a supersonic super-cooled free jet; and wherein that jet is exposed to laser photons at wavelengths that selectively excite predetermined molecules iQF6 to iQF6*, thereby inducing rapid VT conversions and dissociations of iQF6*:G?iQF6+G+kT, while leaving non-excited dimers jQF6:G intact; and wherein a skimmer separates the supersonic free-jet core stream containing heavier jQF6:G dimers from lighter core-escaped iQF6-enriched rim gases.

Abstract: An advanced communications system comprising an emitter and an improved receiver (detector) utilizing modulated beams of neutrino and antineutrino waves as information carriers between the emitter and the receiver. Generation of modulated neutrino and antineutrino beams in the emitter is achieved by a laser-like medium, while detection and demodulation of the neutrino and antineutrino beams is accomplished by a second laser-like medium which registers the flux (or fluence) of modulated neutrinos and antineutrinos passing there-through by means of resonant stimulated deexcitation of lasable excited states. In addition to the information transmission utilization, the neutrino emitter and receiver (detector) system may also be employed to gather information by the probing of internal earth structures.

Abstract: Nozzle cooling and wall contact prevention control are included in a gaseous CRISLA apparatus, along with removable collectors, and the efficient use of one or more currently available high power lasers to produce a commercially economic isotope separation process. The wall contact prevention is accomplished with gaseous boundary layers, and a supersonic nozzle normally is used to cool and separate excitation bands of the isotopic material. Non-intermixing gaseous streams with different isotopic assays can be created in a single nozzle chamber and segmented collection chamber, which along with recirculation loops and compressors, allows a single laser system and a single nozzle system to be used to selectively excite the isotopic material while it makes multiple passes through the laser beams of the laser system until only a small fraction of the desired isotope remains to be separated. The process is especially effective in separating .sup.235 UF.sub.6 from a gaseous mixture of .sup.235 UF.sub.6 and .sup.

Abstract: Selection criteria are disclosed for choosing a coreactant RX that will improve the isotope separation in laser-activated chemical reactions which may proceed by the steps: ##STR1## The step of coreactant activation can be important in some exchange reactions but unnecessary in others. That is for some laser-activated chemical reactions, the second step may be absent.The selection criteria are based on the relative magnitudes of the bond-energies and therefore vibrational frequencies in the molecules .sup.i MY and RX, and the requirements for forming a Vanderwaals-like attachment complex. Also, the upper and lower limit of tolerable thermal (non-laser) reaction speeds are defined. It is shown further that it is necessary to restrict suitable RX candidates to those species which yield .sup.i MX product that does not participate in subsequent chemical reactions which cause isotope scrambling. The employment of a second auxiliary coreactant is recommended in certain cases if its interaction with the complex (.

The chemical compound containing the atoms of the isotope to be separated may be subsequently processed to obtain the isotope.

Abstract: A communication system comprising an emitter and a receiver (detector) utilizing modulated beams of neutrino and antineutrino waves as information carriers between the emitter and the receiver. Generation of modulated neutrino and antineutrino beams in the emitter is achieved by a maser-like medium, while detection and demodulation of the neutrino and antineutrino beams is accomplished by a second maser-like medium which registers the fluence (or flux) of modulated neutrinos and antineutrinos passing therethrough by means of resonant stimulated deexcitation of excited states. In addition to the information transmission utilization, the neutrino emitter and receiver (detector) system may also be employed to gather information by the probing of internal earth structures.
