摘要：

Neutron irradiation GaS and GaSe single crystals have been investigated by positron lifetime and Doppler broadening measurements. The samples were irradiated at fluences yielding estimated Ge concentrations within 2.5x10(15) and 2x10(16) cm(-3). The positron annihilation parameters (average lifetime, tau(m), and parameter S) have shown a saturation effect with increasing radiation doses. A second lifetime component was found of 335 ps in GaSe and of 330 ps in GaS. These lifetimes have been associated to Ga-monovacancy related defects.
