Shubnikov-de Haas oscillations in selectively doped GaAs single quantum wells with AlAs/GaAs superlattice barriers has been studied at temperature T=4.2 K in magnetic fields B<1 T. High-mobility heterostructures with thin spacer had been grown by molecular-beam epitaxy on (001) GaAs substrates. The mobilities of two-dimensional electron gas measured in two crystallographic directions [110] and [110] differ from each other more than 50%. Properly adapted expression for Shubnikov-de Haas oscillations amplitudes in anisotropic samples has been used for correct analysis of this oscillations. It was stated that quantum life-time in our heterostructures as measured by Shubnikov-de Haas oscillations on Hall bars oriented in the directions [110] and [110] varies less than 5%. Obtained results show that quantum life-time in two-dimensional electron system with anisotropic mobility is isotropic with aforementioned accuracy. Keywords: Shubnikov-de Haas oscillations, anisotropic mobility, quantum life-time, superlattice barriers.
