    "abstract": "Parity (P) and time (T) invariance violating effects in the Ra atom are\nstrongly enhanced due to close states of opposite parity, the large nuclear\ncharge Z and the collective nature of P,T-odd nuclear moments. We have\nperformed calculations of the atomic electric dipole moments (EDM) produced by\nthe electron EDM and the nuclear magnetic quadrupole and Schiff moments. We\nhave also calculated the effects of parity non-conservation produced by the\nnuclear anapole moment and the weak charge. Our results show that as a rule the\nvalues of these effects are much larger than those considered so far in other\natoms (enhancement is up to 10^5 times).",
