Chiral invariant phase-space decay can be used to de-excite an excited hadronic system. This possibility can be exploited to replace the intra-nuclear cascading after a high energy primary interaction takes place. The basic assumption in this is that the energy loss of the high energy hadron in nuclear matter is approximately constant per unit path length (about 1 GeV/fm). This energy is extracted from the soft part of the particle spectrum of the primary interaction, and from particles with formation times that place them within the nuclear boundaries.
Several approaches of transfering this energy into quasmons were studied, and comparisons with energy spectra of particles emitted in the backward hemisphere were made for a range of materials. Best results were achieved with a model that creates one quasmon per particle absorbed in the nucleus.
