Abstract
A pseudopotential method describing the alkali-core and the configuration-interaction method are used to obtain the lowest 1,3 Sigma g,u+ states of Na2 and K2. For the ground states of Na2 the authors find reasonable agreement with experimental estimates of the dissociation energies. Wells followed by bumps were predicted for the 3 Sigma u excited states dissociating to Na(3s)+Na(3p) and K(4s)+K(4p). Double minima for the 1 Sigma u states dissociating to Na(3s)+Na(4s) and K(4s)+K(5s) are reported.Keywords
