We perform spectrally resolved degenerate four wave mixing (DFWM) measurements by resonantly exciting 1s heavy hole excitons in 8 and 17:5 nm wide GaAs multiple quantum wells (MQW) with subpicosecond laser pulses. The signal is detected in a self-di raction mode in backward geometry. The DFWM spectr
