Schiff moments of deformed nuclei

Stimulated by the recent suggestion of using a europium compound for the Cosmic Axion Spin Precession Experiment search for axionlike dark matter, I develop a new method for accurate calculation of Schiff moments of even-odd deformed nuclei. The method is based on experimental data on magnetic moments and E1 and E3 transition amplitudes in the given even-odd nucleus and in adjacent even-even nuclei. Despite the fact that such data sets are not yet available for a lot of the interesting nuclei, the full set of data is available for ^153Eu. Hence, I perform the calculation for ^153Eu and find the value of the Schiff moment. The value is about 30 times larger than a typical Schiff moment of a spherical heavy nucleus. The enhancement of the Schiff moment in ^153Eu is related to the low-energy octupole mode. On the other hand the value of the Schiff moment I find is 30 times smaller than that obtained under the assumption of a static octupole deformation.
