Allowed vibronic transitions to the two lowest singlet electronic terms induced by electron impact in the cesium dimer are theoretically investigated in the frame of the semiclassical impact parameter method. All relevant quantities characterizing the transitions, i.e., transition dipole moments, Franck-Condon factors, and vibronic moments, are derived and compared with results in the literature. Total and vibrationally resolved cross sections for excitations initiated from. v '' = 0-45 vibrational levels of the ground electronic state are calculated and the role of vibrational excitation is discussed.
