Abstract

We show that the measured intrinsic octupole moments of 220^{220}Rn, 224^{224}Ra, and 226^{226}Ra constrain the intrinsic Schiff moments of 225^{225}Ra221^{221}Rn, 223^{223}Rn, 223^{223}Fr, 225^{225}Ra, and 229^{229}Pa. 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 non-invariant interaction produced by CP-violating fundamental physics. Those matrix elements are also correlated with octupole moments, but with a larger systematic uncertainty.
