Abstract : Effective techniques leading from the values of the crystal structure invariants to the values of the individual phases have recently been obtained. In the present report a new formula expressing the structure invariants in terms of the observed crystal structure amplitudes is given, and a computer program is described which facilitates the computation of the invariants.
