Abstract :
The so-called P1 structural parameter is well-known as an index for estimating the degree of graphitization, which was proposed by Houska and Warren. The parameter denotes the probability of finding a graphitic stacking relation between the adjacent carbon layer planes and was generally estimated by an inverse Fourier transform based on their theory. However, in their method, the Fourier integration range is too narrow to evaluate the Fourier coefficients precisely and to discuss in detail the P1 values obtained from them. In the present study, a newly developed estimation method for the degree of graphitization with higher accuracy using the least square refinement method was presented and the obtained results were compared with those obtained using the conventional inverse Fourier method. The developed program for the analysis will be released in near future.
