The alignment correlation terms in the β-ray angular distributions from spin aligned 8Li and 8B have been measured precisely. The difference of these terms between the mirror pair is compared with the prediction. As a result, the G-parity violating induced tensor term is found to be small. The significant contribution from the second-forbidden matrix elements is shown by comparing with the β-α correlation coefficients.
