In this work we have investigated total fission cross section of 181 Ta+ 1 H at FRS (FRagment Separator -GSI) at 1, 0.8, 0.5 and 0.3 GeV with an specific setup, providing high accuracy measurements of the cross section values. We compare the results obtained in this experiment, with several calculations performed with the intra-nuclear cascade model (INCL v4.1) coupled to de-excitation code (ABLAv3p), according to two different models describing fission process at high-excitation energies:

The comparison with data of previous experiments is also discussed in order to address the existing discrepancies with this new results.
