Theoretical determination of highly excited states of K2 correlated adiabatically above K4p + K4p.
The electronic structure of the K(2) molecule is revisited to describe the 36 highly excited states dissociating into the three limits K(4s) + K(4f), K(4s) + K(6p), and K(4s) + K(5d), which have not yet been investigated theoretically. Potential energy curves and spectroscopic constants are (re)displayed for the 98(1,3)Lambda(g,u) ((+,-)) molecular states correlated adiabatically to the limits up to K(4s) + K(5d). For the 10 states dissociating adiabatically into K(4p) + K(4p) and limits above for which experimental data are available, averaged errors of present results are found to be Delta R(e) = 0.07a(0), Delta T(e) = 50 cm(-1), Delta omega(e) = 0.8 cm(-1) and Delta D(e) = 60 cm(-1).
