METHOD OF PRODUCING NICKEL-63 RADIONUCLIDE Russian patent published in 2017 - IPC G21G1/00 

FIELD: chemistry.

SUBSTANCE: method includes heating the metallic nickel-containing radionuclide ⁶³Ni up to its evaporation temperature in a vacuum chamber, a target three-selective photoionization of Ni isotope atoms by means of simultaneous pulsed irradiation of the atoms by spatially combined laser beams with a wavelength of 3222.566±0.001Å, 5464.006±0.001Å and 5442.195±0.001Å with the subsequent isolation of the photoions ⁶³Ni by electric field. The method is carried out at a pulsed laser beam frequency of 5-20 kHz with a pulse duration of 20-100 nsec, and the average laser radiation pulse power density of the first stage is selected in the range 40÷100 mW/cm², of the second stage - 5÷40 mW/cm², of the third stage - 3÷5W/cm² at a pulsed laser beam frequency of 10 kHz with the pulse duration of 20 nsec.

EFFECT: possibility of implementing the method allowing to carry out the simultaneous selection of highly-enriched radionuclides and applying it to substrates at a commercial scale.
