摘要： A method of producing excited states of atomic nuclei which comprises bombarding atoms with X rays or electrons, characterized in that (1) in the atoms selected to be produced in the excited state of their nuclei, (a) the difference between the nuclear excitation energy and the difference between the binding energies of adequately selected two electron orbits is small enough to introduce the nuclear excitation by electron transition, and (b) the system of the nucleus and the electrons in the case of ionizing an orbital electron in said atoms should satisfy the spin and parity conservation laws, and (2) the energy of the bombarding X rays or electrons should be larger than the binding energy of one of the said two electron orbits which is located at shorter distance from the atomic nucleus. According to the present invention, atomic nuclei can be excited in a relatively simple manner without requiring the use of large scale apparatus, equipment and production facilities, e.g., factories. It is also possible to produce radioactive substances or separate a particular isotope with an extremely high purity from a mixture of isotopes by utilizing nuclear excitation.

摘要： A system, apparatus and process for separating a tritiated heavy water stream into a tritium-lean heavy water stream and a tritium-enriched heavy water stream. Tritiated heavy water (DTO/D2O) is fed to a mid-point of an isotope exchange column. The column contains a hydrophobic solid catalyst to promote exchange of deuterium and tritium. DT/D2 gas flows out of an electrolysis cell and into the first end of the column, concentrating tritium content in the heavy water by counter current flow to produce a tritium-rich heavy water below the feed point and a tritium-lean deuterium gas above. Tritium-rich heavy water flows out the first end of the column and into the electrolysis cell, forming DT/D2 gas and a tritium-enriched heavy water stream. Tritium-lean deuterium gas flows out the second end of the column and into a tritium-lean heavy water unit. Either O2 gas or light water additionally flows into the tritium-lean heavy water unit to form a tritium-lean heavy water.

摘要： The method for concentrating an oxygen isotope or isotopes of the present invention combines the step of concentrating 17O and/or the step of depleting 18O that utilizes photodissociation of ozone by a laser beam with an oxygen distillation step that concentrates the oxygen isotope. At this time, it is preferable to carry out a step of isotope scrambling in addition to the above. When both a step of concentrating 17O and a step of depleting 18O are carried out, whichever thereof may be done first prior to the other. Also these steps may be placed either before or after the oxygen distillation step. Moreover, at least one of said oxygen distillation step, the concentrating 17O step, the depleting 18O step and the isotope scrambling step is preferably carried out twice or more.
