Abstract: We show that the measured intrinsic octupole moments of Rn-220, Ra-224, and Ra-226 constrain the intrinsic Schiff moments of Ra-225, Rn-221, Rn-223, Fr-223, Ra-225, and Pa-229. The result is a dramatically reduced uncertainty in intrinsic Schiff moments. Direct measurements of octupole moments in odd nuclei will reduce the uncertainty even more. The only significant source of nuclear-physics error in the laboratory Schiff moments will then be the intrinsic matrix elements of the time-reversal noninvariant interaction produced by CP-violating fundamental physics. Those matrix elements are also correlated with octupole moments, but with a larger systematic uncertainty.
