To date, there have been a considerable number of reports and investigations regarding accounts of stable isotopic fractionations and variation of stable isotope ratios. These descriptions depend only on biological activities, a little bit of differences of kinetic ratios of chemical reactions and a little differences of physical development. Although the relationship between the phenomena of stable isotopic fractionations or variation of stable isotope ratios and electric charge or electric field or electromagnetic forces has never been considered. Furthermore the relationship between the phenomena of variation of stable isotope ratios and cosmic-ray bombardment (spallation effect) also has never been considered. The object of this investigation is to discover the reason for variations in isotopic ratios in the environment to adapt the previous studies as follows. [ A ] Neutron bombardment from cosmic radiation (spallation effect) [ B ] Oddo-Harkins Rule [ C ] All kinds of isotopes have specific electrical potential [ D ] Previous study of Production of 7Be by nuclear spallation reactions
