    "abstract": "A Cs fountain electron electric dipole moment (EDM) experiment using\nelectric-field quantization is demonstrated. With magnetic fields reduced to\n200 pT or less, the electric field lifts the degeneracy between hyperfine\nlevels of different|mF| and, along with the slow beam and fountain geometry,\nsuppresses systematics from motional magnetic fields. Transitions are induced\nand the atoms polarized and analyzed in field-free regions. The feasibility of\nreaching a sensitivity to an electron EDM of 2 x 10 exp(-50) C-m [1.3 x 10\nexp(-29) e-cm] in a cesium fountain experiment is discussed.",
