Peculiar shape of the curve showing the intensities of the non-diagram lilies of Kα series as a function of atomic number has been reported by C. H. SHOW and L. G. PARRATT, and M. SAWADA and J. KAKINOKI.
And also noticeable change in intensity was observed in non-diagram lines of F(9) in various compounds by M. SAWADA, Z. FURUTA and J. KOSUGI.
To explain these curious dependency on atomic number, estimations was carried out for the probability of the de-excitation of the doubly ionized state which was customary believed to be the initial state of these non-diagram lines. On the basis of the idea of the de-excitation of doubly ionized state, takink into consideration of the de-excitation the shape of the above-nientioned curve was explained qualitatively
