The β-ray angular distribution from the purely aligned nuclei, 20F(Iπ = 2+, T1/2 = 11.00s) and 20Na(Iπ = 2+, T1/2 = 447.9ms), have been measured to test the G symmetry in the weak nuclear currents. The alignment terms α± of mirror pair in the mass number A = 20 system have been obtained as a function of β-ray energy with the preliminary analysis.
