This paper presents a method of eliminating the affects of the time resolution function in the positron annihilation lifetime spectrum fitted with a multi-exponential function. The peeling method has been used to estimate initial value of the parameters
then the iterative process in Gauss-Newton's method is easily converged. The program (PLSEF) has been worked out. Its reliability and applicability has been shown in its applications.
