Based on the classical quantum-mechanical approach, the physical mechanism of isotope fractionation is proposed associated with the predominance of a certain number of neutrons among nucleons and explaining the nonequilibrium accumulation of certain stable isotope shapes of biogenic elements in heterogeneous systems. The effect may be due to the interaction of the magnetic moments of atomic nuclei and valence electrons leading to a change in the distance between them, including the influence of the changed distance between atoms, on the energy of the covalent link between the pairs of atoms.

原子核同位素组成对共价键能量的影响

基于经典的量子力学方法，提出了同位素分馏的物理机制，与核子中一定数量的中子有关，并解释了异质系统中生物元素某些稳定同位素形状的非平衡积累。该影响可能是由于原子核的磁矩与价电子的相互作用导致它们之间的距离发生变化，包括原子之间距离的变化对成对原子之间的共价键的能量的影响。 。
