Approximate Estimation of the Degree of Lanthanide Tetrad Effect from Precise but Partially Void Data Measured by Isotope Dilution and an Electron Configuration Model to Explain the Tetrad Phenomenon

抄録

We have succeeded in evaluating mathematically the relative magnitude of lanthanide tetrad effects for four subgroups of lanthanides. Our new mathematical method was applied to two kinds of data; (1) the results secured by water-rock interaction in the laboratory and (2) the data on a ground water running from cracks of rock wall in a tunnel as well as a probably related granitic rock. The resultant numerical values of quadratic coefficients pertaining to the tetrad phenomenon are expected to be of importance.
Further, a new simple model accountable for the tetrad phenomenon observed in a variety of physical and chemical phases is proposed about the 4felectron configuration. It will also give any clue or impetus to a wide scope of sciences ranging from quantum mechanics to geological sciences.
