Photoluminescence (PL) spectra of an MBE-grown symmetric 10 nm wide double quantum well located in the intrinsic region of a p-i-n diode were investigated in electric and magnetic ÿelds. In addition to the commonly reported spatially direct (DX) and indirect transitions, we observed in the spectra a
