Abstract：
A new measurement method of characteristic lifetime of positron annihilation in mercury cadmium telluride(MCT)in thermoequilibrium was proposed.A result of τ_b,the annihilation lifetime of positrons in bulk state in HgCdTe,being 277±1ps,and τ_d,the lifetime of positrons trapped in mercury vacancies,being 306±2pswas obtained.The result was discussed and compared with that from other methods.
