Separation of B10 and B11 isotopes in a strong infrared CO2 laser radiation field

The results are given of experiments in which the B¹⁰ and B¹¹ isotopes were separated in a strong (~10⁹ W/cm²) CO₂ laser radiation field which excited BCl₃ molecules with natural relative abundances of the boron isotopes. The B¹⁰Cl₃ or B¹¹Cl₃ molecules were dissociated in the CO₂ laser radiation field and this was followed by the reactions of the dissociation products with various acceptors. The acceptors were O₂, HBr, C₂D₂, NO, and H₂. The dependences of the enrichment coefficient on the BCl₃, and acceptor pressures were determined. The separation efficiency was found and it amounted up to 25% of the molecules of the excited isotopic composition in the reaction zone for each radiation pulse.
