A slowing down model is a simple representation of the angle-integrated Boltzmann equation whereby energy loss in collisions is taken into account in some kind of approximation, which may be made quite good. Probably the greatest advantage in using a slowing down model lies in its replacement by a simple first- order differential equation in energy of the original integral equation for which there are no known mathematical methods of obtaining a solution in closed form. From this differential equation, explicit solutions for flux spectra can be calculated. Several slowing down models are exhibited and an idea of their accuracy is given. (auth)
