Abstract：

A dynamical statistical model is used to analyze the experimental shape isomer yields data in the reaction d+²⁴⁰Pu atE=20—29 MeV. The possibility of determining the nuclear dissipation is discussed. Comparison of the experimental data with the calculations leads to a value of the reduced dissipation coefficientβ=0.45×10²¹s^－1for the Am isotopes.
