Abstract
A semiclassical description is presented for light particle emission from composite systems with a time-dependent shape. With nuclear shapes as a function of time taken from the Feldmeier one-body dissipation code the author calculates the multiplicities of light particles accompanying fission for intermediate systems with A=150-160 having excitation energies of 100 to 300 MeV. The calculations are consistent with experimental data for neutrons. For a good description of the charged particle multiplicities, one has to assume that particle separation energies reflect the structure of two nuclei making the composite system rather than that of the mononucleus.
