Abstract

The nature of the phenomena of K-absorption of X-ray by zinc was investigated and found that the phenomena consist of a main process, and an auxiliary one; the former is the electron transition from k-shell or the level, (1s)21S0, to the opticallevel, (4s, 4p)1P1, ZnI, resulting so called K-absorption main edge; the latter, in nature, is Auger effect, giving rise to some breadth to the K-absorption edge, the emission lines, Kβ2 and Kβ''', and to a fine structure of the main edge itself. The nature of L-abdsrption of X-ray by zinc was also studied and found that the main process is the electron transition from L11, 111 to the optical level of the triplet system of ZnI, (4s, 6s) 3S1, and the auxiliary one is the electron transitions between the levels, belonging to the triplet system of ZnI, K-and L11, 111 -absorptions in zinc oxide were also descrived. In these cases, the main processes are the same as in the cases of zinc respectively, but auxiliary ones consist of the electron transitions between atomic levels of oxygen of ZnO; this causes the shifting of the absorption edges.
