The physical regularities that lead to isotope fractionation and to the accumulation of certain isotope forms in the intercellular and intracellular space at various levels of biological objects were studied. A new hypothesis of fractionation of stable isotopes in biological objects through the neutron effect was discussed. The following feature is noted: it is very likely that the development of isotope shock in living beings is observed mainly in the presence of covalent bonds between atoms with an uncompensated neutron. One possible explanation for this phenomenon can be associated with a change in the physical parameters of the following events: the interactions of the magnetic moments of valence electrons with the magnetic moments of atomic nuclei and the interactions of magnetic moments of atomic nuclei, which result in a change in the distance between atomic nuclei.

化学键中存在未补偿中子时稳定同位素与生物体相互作用的机制

研究了导致同位素分馏和某些同位素形式在不同水平生物对象的细胞间和细胞内空间中积累的物理规律。讨论了通过中子效应分离生物物体中稳定同位素的新假设。注意到以下特征：很可能观察到生物同位素激波的发展主要是在原子与未补偿中子之间存在共价键的情况下。对这种现象的一种可能解释可能与以下事件的物理参数的变化有关：价电子磁矩与原子核磁矩的相互作用以及原子核磁矩的相互作用，
