The parameters are defined through the ν-th order moment of the Fourier transform of the profile function. The exact solutions about typical model profile functions and theoretical size-broadening profile with statistical size-distribution are presented. Examination of the difference between the theoretical size-broadening profile and the Lorentzian function with the common sharpness parameters suggests that the order of ν = -1/2 is suitable to approximate the size-broadening profile with alternative model functions., application/pdf}, pages = {1--11}, title = {粉末回折ピーク形状の「尖り度」を特徴づける新しいパラメータ}, volume = {6}, year = {2007}, yomi = {イダ, タカシ} }
