Abstract：
Spin-polarized fragments ¹⁴B and ¹⁵B produced in the intermediate energy projectile fragmentation reaction were implanted in Mg single crystal,and the electric quadrupole moments Φ for ¹⁴B and ¹⁵B were determined by the β-NMR spectroscopy.The results obtained are |Φ(¹⁴B)|=29.84±0.75mb and |Φ(¹⁵B)|=38.01±1.08mb,which are compared with shell model calculations.
