The alignment correlation term in the β-ray angular distribution from nuclear-spin aligned 20Na(Iπ = 2+, T1/2 = 449.7 ms) has been measured for the first time. A large enhancement of the time component d in the main axial vector current was preliminarily obtained and the higher order matrices j2 and j3 were also evaluated. In order to extract very small G-parity violating induced tensor term, the alignment correlation term of the mirror partner 20F have to be measured.
