Towards the search of T,P-odd interactions in lead monofluoride, PbF

Abstract

The relativistic coupled-clusters method combined with the generalized relativistic effective core potential approach and nonvariational one-center restoration technique is applied to evaluation of parameters of spin-rotational effective Hamiltonian in lead monofluoride to study the effects of violation of time-reversal invariance (T) and space parity (P) in PbF. The obtained hyperfine structure constants, A${}_{||}$=9942 MHz and A${}_{\perp }$=-7174 MHz are stable with respect to the improvement of the correlation treatment and they are in a very good agreement with the experimental data, A${}_{||}$=10147 MHz and A${}_{\perp }$=-7264 MHz [PRA {\bf 84}, 022508 (2011)]. This is essential to the important task of verifying the value of effective electric field \Eeff =40 GV/cm, the parameter of P-odd interaction $W_P$=-1213 Hz and the parameter of T,P-odd pseudoscalar$-$scalar electron$-$nucleus interaction $W_{T,P}$=91 kHz, which are of primary interest in the paper.
