Transport Coefficients Within a Fourier Shape Parametrization

International audienceTransport coefficients, such as the collective potential, inertia, friction and diffusion tensors, that are required in any dynamical description of the fission process are reviewed. These are mandatory when solving e.g. the Langevin equation that allows to follow the time evolution of a deformed, hot rotating nucleus from its formation in a heavy-ion collision up to the scission instability. The present study is carried out using a new shape parametrization which we have developed and which is based on a Fourier expansion of the nuclear shape functio
