By the method of capacitance spectroscopy and of magnetotransport we have investigated the = 1 3 and 2 3 fractionalquantum-Hall-e ect (FQHE) states in gated GaAs=AlGaAs heterojunctions with tuned electron areal density. Our experimental results conΓΏrm the theoretical prediction of the fractional qua
