MICHIGAN STATE UNIVERSITY (MSU) DEVELOPS ADVANCED MODELS OF NUCLEAR FISSION BASED ON NUCLEAR DENSITY FUNCTIONAL THEORY AND ITS TIME-DEPENDENT EXTENSIONS. THEY WILL CARRY OUT GLOBAL CALCULATION OF (I) FISSION YIELDS USED IN ASTROPHYSICAL SIMULATIONS OF R-PROCESS NUCLEOSYNTHESIS AND (II) FISSION LIFETIMES OF ACTINIDE AND TRANSACTINIDE NUCLEI. THE FISSION CODES DEVELOPED UNDER THIS PROPOSAL WILL BE FREELY USED BY NNSA RESEARCHERS AND, GENERALLY, BY THE LOW-ENERGY NUCLEAR PHYSICS COMMUNITY. MSU WILL TRAIN JUNIOR SCIENTISTS AND STUDENTS TO APPLY NUCLEAR MANY-BODY TECHNIQUES TO DESCRIBE NUCLEAR FISSION AND OTHER LOW-ENERGY NUCLEAR PHENOMENA.
