Abstract
The sign of the quadrupole coupling constant eqQ of B-8 in ZrB2 is determin ed to be positive through the beta-delayed alpha-ray anisotropy measurement combined with the spin manipulation technique by use of the beta-NMR. Acco rding to the theoretical calculation of the electric field gradient in ZrB2 , the sign of the quadrupole moment of B-8 is deduced to be positive.
