Abstract : A set of expressions is presented for calculating structure-factors and least-squares coefficients for cubic structures with isotropic temperature factors. These expressions have been utilized in programming the Burroughs 220 and IBM 7090 computers to perform structure-factor least-squares calculations for any cubic space group; to direct the course of calculations for a particular space group, only the space group number need be designated. The expressions complement those presented by Hybl and Marsh for the orthorhombic system.
