A note on the probability distribution of phases in a non-centrosymmetric crystal with a degree of centrosymmetry. II. The case of a crystal with type-II degree of centrosymmetry

The nomenclature and parameters needed for characterizing two different types of degrees of centrosymmetry in a non-centrosymmetric crystal are introduced. The probability distribution of the phase angles of reflexions for the type-II case is worked out and this is used to obtain the probable fraction of reflexions for which the magnitude of the phase angles would deviate from the centrosymmetric values of 0 or π by any given amount α₀ corresponding to different type-II degrees of centrosymmetry.
