Abstract
A formalism for semi-adiabatic cranking mass parameters is presented. For the fission process of 234U, the time-dependent pairing equations of motion are used to calculate the excitation energy and to extract values of the cranking inertia. A fission barrier is determined by minimizing the action trajectory in a five-dimensional configuration space spanned by elongation, necking, deformations of fragments and mass asymmetry. The deformation energy is computed in the frame of the microscopic–macroscopic model. The two-center shell model with Woods–Saxon potentials is used in this context. Values of the inertia for excited fissioning systems are reported. A dependence between the cranking mass parameters and the intrinsic excitation energy is evidenced.
