摘要

Cross sections for vibrational excitation (VE) of the X 1 Sigma (+) sub g state of Li2 via formation of the excited A 1 Sigma (+) sub u or B 1 Pi sub u electronic states are reported. For VE through the A 1 Sigma (+) sub u state, the cross sections are nearly constant for forming X 1 Sigma (+) sub g (3 approx. < nu approx. <9) via electron collisional excitation. For photon pumping (600 approx. < lambda approx. < 700 nm) of the A 1 Sigma (+) sub u state, levels nu < or = 9 are predominantly formed. VE via the B 1 Pi sub u state has a lower probability.
