摘要：

The positron lifetime is related to the temperature in C-60, i.e. the positron lifetime increases as a function of increasing temperature between 10 and 300 K. In this paper we adopted the extended Su-Schrieffer-Heeger model; by using the method of the Green function at a finite temperature, we then deduce a relation between the positron lifetime and temperature. The results show that the theoretical calculation may be in accordance with experiment.
