Abstract: The defects of β-BaB2O4 single crystals were studied by means of the positron annihilation lifetime spectrum method for the first time. And the fo rmation of the defects were discussed in relation to the crystal growth conditions and annealing treatments.

Key words: crystal growth, barium metaborate, crystal defects, positron annihilation
