Analysis of n+Th-232 interaction up to 200 MeV

摘要

Observed fission cross section data are reproduced up to E-n similar to 200 MeV within Hauser-Feshbach pre-equilibrium model. Symmetric and asymmetric fission mode partitioning of the observed fission cross section is predicted. Fission barriers of neutron-deficient Th nuclides are compared with the microscopic and macroscopic-microscopic calculations. Nucleon optical model potential for Th-232 is obtained. Rigid rotator coupled-channel model reproduces experimental neutron total cross section data up to 200 MeV. (c) 2005 Elsevier B.V All rights reserved.
