Correlating Schiff moments in the light actinides with octupole moments
Abstract
We show that the measured intrinsic octupole moments of 220Rn, 224Ra, and 226Ra constrain the intrinsic Schiff moments of 225Ra221Rn, 223Rn, 223Fr, 225Ra, and 229Pa. 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.
