Comment on ``Inverse exciton series in the optical decay of an excitonic molecule''

I. S. Gorban, M. M. Bilyi, I. M. Dmitruk +1

Tokunaga et al. [Phys. Rev. B Vol. 59, R7837 (1999)] claim the first successful observation of the inverse exciton M series in the emission spectrum of excitonic molecules. We asse…
