Application of Monte-Carlo method to calculate the substrate effect in the lifetime spectrum of positron annihilation
Monte-Carlo method was applied to calculate the annihilation probabilities ofpositrons from 22Na in Mylar and Ni films with different thickness. Results ofsubstrate effects of Mylar films with different thickness for sample of Si
Fe
PE andPP were obtained. The results showed that the substrate effects for samples PE andPP were stronger than those for Si and Fe. Therefore it is feasible for usingMonte-Carlo method to calculate substrate effect.
