Phosphorus(V) Oxoacid Derivatives as Efficient Ligands for Boron Isotope Separation by Chemical Exchange Method

摘要

Boron isotopes are widely used in different fields of science and technology due to their significantly different nuclear properties. Light boron isotope ~(10)B has a large neutron capture cross-section in reaction ~(10)B (n, a) ~7Li of 3820 barn for neutrons with average energy 0.025 eV (thermal neutrons), while this value for heavy boron isotope ~(11)B is not higher than 0.05 barn [1]. Isotope ~(10)B is of the most practical interest because of wide application of compounds enriched with this isotope in nuclear power, nuclear engineering industry, nuclear instrument engineering, nuclear medicine [2,3].
