Total fission cross sections of 181Ta ions colliding with hydrogen atoms at 300, 500, 800, and 1000 A MeV have been measured. The combined use of the inverse kinematics technique with an efficient detection set-up made it possible to determine these cross sections with high accuracy ranging between 8% and 17%. The new data put some light in the controversial results obtained so far and contribute to the understanding of the fission process at high excitation energies.
