M. Braun et V. Engel, PUMP PROBE DIRECT PHOTOIONIZATION FROM THERMALLY HOT SAMPLES - THE CS-2 MOLECULE/, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 39(4), 1997, pp. 301-307
We investigate the femtosecond photoionization of Cs-2 within a model
including four electronic states. A thermally broad initial state dist
ribution influences the time-dependence of the transient ion signals c
rucially. We show that even for the present case of simple one-dimensi
onal motion the interpretation of ionization signals requires special
care under certain experimental conditions. The results are compared t
o recent experimental data and a modified ionic state potential is con
structed.
