Low-lying exciton levels in a strong magnetic field

The behavior of the n = 2 and n = 3 exciton levels in a strong magnetic field is analyzed for the case in which the spacing between the Coulomb levels is much greater than that between Landau levels. The results are compared with experimental data on magnetooptical absorption in Cu₂O. The observed splitting of these levels can be attributed to the appearance of a Landau series above the Coulomb levels.Translated from Izvestiya VUZ. Fizika, No. 2, pp. 7–11, February, 1970.
