CALCULATION OF INTERACTION POTENTIALS FOR EXCITED ALKALI ATOM-MERCURYATOM SYSTEMS - THE K-ASTERISK-HG INTERACTION

Interatomic potentials for the systems alkali atom (in the ground and excited states)-mercury atom are calculated by the effective potential method using a polarization potential obtained from calculation of mo st important polarization diagrams of perturbation theory in the Thoma s-Fermi approximation. The results are used to calculate the quasimole cular terms of the A-Hg systems, where A = Na, K. Some values of the i nteraction potential parameters are published for the first time. The results obtained in this work are compared with the available experime ntal and theoretical data.
