ON THE TWO GAS COMPONENT EXCITON MODELEnte Nazionale Energie Alternative, Divisione di Calcolo 40138 BOLOGNA, ITALY The two-component exciton model is reformulated to facilitate a solution of the master equation and to express transition rates via quasiparticle state densities calculated in the frame of the shell model. On this basis, flux flow between different substages of the composite nucleus is discussed. This analysis shows strong discrepancies in the strength of various transitions. In particular, particle-hole creation by a hole is found to be rather negligible. KEYWORDS: exciton model, state density, composite system equilibration |
