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