Potential energy curves for the interaction of Ag(5s) and Ag(5p) with noble gas atoms [PDF]

open access: yes, 2013
We investigate the interaction of ground and excited states of a silver atom with noble gases (NG), including helium. Born-Oppenheimer potential energy curves are calculated with quantum chemistry methods and spin-orbit effects in the excited states are ...
