An adiabatic study of theXthinsp;1Sgr;+andAthinsp;1Sgr;+states of BeH+

摘要

Using a 330hyphen;term configurationalhyphen;interaction wave function with an elliptical orbital basis, the potential curves for the electronic ground state (Xthinsp;1Sgr;+), and first excited state (Athinsp;1Sgr;+) of BeH+have been determined. For theXthinsp;1Sgr;+state the curve is close to the best hitherto published and for theAthinsp;1Sgr;+the curve is better than any previous results. With the corresponding wave functions, the adiabatic corrections to these curves have been found for the first time.
