The excitonic spectrum of germanium in a strong magnetic field

As was found in recently reported experiments with the uniaxially deformed germanium in a magnetic field [7], sufficiently strong intensity of the applied magnetic field results in the appearance of a new line in the optical spectrum of the excitons. We propose a mechanism which can provide explanation of this experimentally observed spectral feature. The new spectral line may be attributed to the formation of strongly bound biex-citonic molecules in the quantum state 3П„.
