Fragments with 4[le][ital Z][le]15 have been studied from the reaction 486, 550, 640, and 730 MeV [sup 86]Kr+[sup 63]Cu. A standard analysis procedure has been used to characterize the associated asymmetric fission barriers and compare them to the Sierk model (Yukawa plus exponential finite range nuclear potential). The predicted YEFRN model barriers are too small by [approx]37%, a result that is in contrast with other studies. The often used statistical model code GEMENI also fails to account for these excitation functions.
