Résumé

Fission excitation functions for ¹⁶O+¹⁴¹Pr, ¹⁶⁵Ho, ¹⁷⁵Lu and ¹⁹⁷Au, for ¹²C+¹⁶⁹Tm and for ²²Ne+²²Ne+¹⁵⁹Tb have been analyzed to determine the excitation energy dependence of the fission probability. As excitation energy increases, this probability reaches a maximum and then decreases monotonically. The results provide new and detailed information on the time distribution of the fission probability and confirm that the bulk of the pre-scission emission occurs prior to the saddle point.
