Improved Cascade-Exciton Model of Nuclear Reactions

Recent improvements to the Cascade-Exciton Model (CEM) of nuclear reactions are briefly described. They concern mainly the cascade stage of reactions and a better description of nuclei during the preequilibrium and evaporation stages of reactions. The development of the CEM concerning fission is given in a separate talk at this conference. The increased accuracy and predictive power of the CEM ...

Cascade-Exciton Model Analysis of Nucleon-Induced Fission Cross Sections of Lead and Bismuth at Energies from 45 to 500 MeV

An extended version of the Cascade-Exciton Model (CEM) of nuclear reactions is applied to analyze nucleon-induced fission cross sections for Bi and Pb nuclei in the 45–500 MeV energy range. The available data on linear momentum transfer are analyzed as well. The results are compared with analytical approximations resulting from a comparative critical analysis of all available experimental data....

Merging the Cem2k and Laqgsm Codes with Gem2 to Describe Fission and Light-fragment Production

We present the current status of the improved Cascade-Exciton Model (CEM) code CEM2k and of the Los Alamos version of the Quark-Gluon String Model code LAQGSM. To describe fission and light-fragment (heavier than He4) production, both CEM2k and LAQGSM have been merged with the GEM2 code of Furihata. We present some results on protonand deuteron-induced spallation, fission, and fragmentation rea...

Complex Particle and Light Fragment Emission in the Cascade-exciton Model of Nuclear Reactions

A brief description of our improvements and refinements that led from the CEM95 version of the CascadeExciton Model (CEM) code to CEM97 and to CEM2k is given. The increased accuracy and predictive power of the code CEM2k are shown by several examples. To describe fission and light-fragment (heavier than He) production, the CEM2k code has been merged with the GEM2 code of Furihata. We present so...

Singlet fission in reduced dimensions of crystals PAUL

Submitted for the MAR14 Meeting of The American Physical Society Singlet fission in reduced dimensions of crystals PAUL TEICHEN, JOEL EAVES, The University of Colorado at Boulder — In some molecular systems the decay of an initially excited singlet into two independent triplets, a process called singlet fission, is highly efficient. Organic crystals are among the most promising candidates for i...
