    "abstract": "We report results of ab initio calculation of the spin-rotational Hamiltonian\nparameters including P- and P,T-odd terms for the BaF molecule. The ground\nstate wave function of BaF molecule is found with the help of the Relativistic\nEffective Core Potential method followed by the restoration of molecular\nfour-component spinors in the core region of barium in the framework of a\nnon-variational procedure. Core polarization effects are included with the help\nof the atomic Many Body Perturbation Theory for Barium atom. For the hyperfine\nconstants the accuracy of this method is about 5-10%.",
