Abstract

In the spectral range between 480 nm and 630 nm the Stark effect of the transitions n 1Q - 2 1S, n 1Q - 2 1P and n 3Q - 2 3 P (n = 3 ÷ 9, Q = S, P, . . .) was studied using electric field up to 1500 kV/cm. For such a high field the Stark splitting becomes greater than the simple structure of the atom. Hence, anticrossings of the Stark components of the same magnetic quantum number occur. The experimental results have been compared with the theoretically determined shifts. The results of calculations show good agreement with observation not only for low field values, but also in high fields and in case of level anticrossings.
