“…These P-and T -odd interactions can induce mixing between opposite parity states and can thus lead to a nonzero dA. Two T-odd nuclear moments are usually taken into account in this context: a nuclear magnetic quadrupole moment (MQM) [33] and a so-called nuclear "Schiff moment" [34][35][36][37][38] At the nuclear level these moments can be generated by P-and T-violating effects such as proton and neutron EDMs and P-and T-violating nucleon-nucleon interactions. For instance, calculations of the MQMs and Schiff moments of various nuclei in terms of the parameters of a general P-and T-odd nucleon-nucleon interaction were made in Ref.…”

The 10-electron generalized relativistic effective core potential and the corresponding correlation spin-orbital basis sets are generated for the Ra atom and the relativistic coupled cluster calculations for the RaO molecule are performed. The main goal of the study is to evaluate the T,P-odd parameter X characterized by the molecular electronic structure and corresponding to a "volume effect" in the interaction of the 225 Ra nucleus Schiff moment with electronic shells of RaO. Our final result for X( 225 RaO) is −7532 which is surprisingly close to that in 205 TlF but has a different sign. The obtained results are discussed and the quality of the calculations is analyzed. The value is of interest for a proposed experiment on RaO [PRA 77, 024501 (2008)] due to a very large expected Schiff moment of the 225 Ra nucleus.

“…The atomic EDM is further enhanced in Ra since the Schiff moment contribution increases faster than Z 2 . In RaF the observable T,P−odd effect associated with the Schiff moment can be expressed in terms of the following effective Hamiltonian [34,35]:…”

Relativistic ab initio calculations have been performed to assess the suitability of RaF for experimental search of P− and T,P−violating interactions. The parameters of P− and T,P−odd terms of the spin-rotational Hamiltonian have been calculated for the 2 Σ electronic ground state of 223 RaF molecule. They include the Wa parameter, which is critical in experimental search for nuclear anapole moment and the parameters W d and WSP required to obtain restrictions on the electric dipole moment of the electron and T,P−odd scalar−pseudoscalar interactions, respectively. The parameter X corresponding to the "volume effect" in the T,P−odd interaction of the 223 Ra nuclear Schiff moment with electronic shells of RaF has also been computed. Spectroscopic and hyperfine structure constants for 223 RaF and 223 Ra + have been computed as well, demonstrating the accuracy of the methods employed.
