摘要： A method for the qualitative or quantitative analysis of isotopes, characterized by bombarding a substance with X rays or electrons of a previously determined dose and energy for analyzing an isotope in the substance to be detected or measured, to produce an excited state of atomic nuclei of the isotope and thereafter detecting the existence or measuring the dose of the gamma rays or internal conversion electrons emitted in the course of the deexcitation process of the atomic nuclei in the excited state to the ground state. According to the present invention, a particular isotope or element in a substance can qualitatively or quantitatively by analyzed in a simple and precise manner within an extremely short period of time without the necessity of using a large scale apparatus.

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.
