Device and method for even-odd separation and ionization of palladium isotopes

An even-odd separation and ionization device of palladium isotopes configured to irradiate a palladium-containing substance including a plurality of types of palladium isotopes with laser beams having a plurality of wavelengths, to selectively ionize palladium isotope having an odd mass number, a plurality of electrons, and a nucleus from the palladium-containing substance, the even-odd separation and ionization device comprising:

• a first laser irradiating device configured to irradiate the palladium-containing substance with a first laser beam having a first wavelength, to excite the palladium isotope at a ground level to a first excited level;
• and
• a second laser irradiating device configured to irradiate the palladium-containing substance with a second laser beam having a second wavelength, to excite the palladium isotope at the first excited level to a second excited level,
• wherein the first and second wavelengths are set such that the first and second laser beams selectively excite the palladium isotope having the odd mass number to the second excited level, and the second excited level becomes an autoionization level, the palladium isotope excited to the second excited level and having the odd mass number has an ion core state of 2D3/2 and the ion core state remains 2D3/2 between the first excited level and the second excited level, where an electron of the plurality of electrons is excited by light absorption, and
• the ion core of the palladium isotope means a combination of the nucleus and the plurality of electrons excluding the electron excited by the light absorption, and the ion core state means an arrangement state of the plurality of electrons in the ion core.
