While sophisticated PB models exist, they require a knowledge of the interaction potentials involved to become predictive. As a first step toward studying the PB at work in OPAL systems, ab initio potential energy surfaces have been generated for a series of combinations of alkali metals (K, Rb, and Cs) and noble gas atoms (He, Ne, and Ar) which potentially may comprise such systems. These surfaces include the ground state $X^2\Sigma_{1/2}^+$, as well as the excited states $A^2\Pi_{1/2}$, $A^2\Pi_{3/2}$, and $B^2\Sigma^+_{1/2}$. They are calculated using the multi-configurational singles and doubles configuration interaction method, including the spin-orbit interaction through the use of two-component pseudopotentials, implemented in the COLUMBUS suite of molecular structure programs. Where possible, results are compared to both experimentally measured and previous theoretical predictions of spectroscopic constants as well as experimentally determined vibrational energy levels. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title POTENTIAL ENERGY SURFACES OF M+NG, M = K, RB, CS AND NG = HE, NE, AR en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
