AB: The temporal evolution of energetic particle beams is studied using the propagating source method. The method was proposed recently [{\it Zank et al.}, 1999, 2000] and is based on the separation of the total particle distribution function into a main beam component (unscattered part) and the secondary component produced by the scattered beam particles. Here, we have generalized the propagating source method, which allows us to map the temporal evolution of the primary beam component more precisely. The result of this change is that it alters the source term in the scattered particle distribution equation and modifies the spectrum. While a more detailed study of the proposed mechanism will be described elsewhere, here we elaborate on the direct implications of the generalization of the propagating source method and discuss how it can be applied to spacecraft measured data directly.
