摘要：

The multiplicities of energetic γ rays have been measured in coincidence with both evaporation residues and fission fragments in the reactions of F19 on Ta181 at projectile energies of 90, 100, 110, 120, 130, and 140 MeV. The experimental data have been compared with results of statistical calculations, which take into account dynamical fission hindrance. The damping of the fission partial width has been determined as a function of excitation energy in Pb200. © 1994 The American Physical Society.
