Correlation between neutron-binding energy and anomalous fractionation of isotopes in medical-biological objects


The isotopic composition of medical-biological objects (MBO) is studied by the method of laser mass spectrometry (LMS). It is found that anomalous fractionation of carbon, oxygen, silicon, sulfur, potassium, and calcium isotopes occurs in MBO. A correlation is established between the neutron binding energy of the isotopes and the anomalous fractionation of isotopes of some elements in MBO.
