Description
Heavy diatomic molecules are currently considered to be among the most sensitive systems used in the search for the P,T-violating effects and in probing of the Standard Model of particle physics. In certain molecules effects resulting from both parity violation and time-reversal violation (P,T - odd effects) are considerably enhanced with respect to atomic systems. The strength of these interactions grows with atomic number, nuclear spin and nuclear deformation. Molecules with atomic nuclear octupole deformation are sensitive for investigating of parity and time-reversal violating effects, in particular nuclear EDM or electric EDM. Diatomic molecules, like AcF and RaF, has been proposed to be sensitive to the various effects, for example, Schiff moment of the nucleus. Nowadays different laboratories plan to perform experimental study of radioactive molecules in aim to measure isotopologue shifts, hyperfine structures and so on.
Pursuing studies on AcF can also provide insight into dynamics of molecular extraction of Ac, as a pathway to delivering a wider range of actinium isotopes for experiments.
This work aims to determine molecular properties of the RaF and AcF at the highest possible level of computational accuracy using the couple cluster in relativistic framework.
The ionization potential, excitation energies, and spectroscopic constants of AcF, RaF will be presented and the uncertainty of the predicted values will be discussed.
