ABSTRACT
ANALYSIS OF CROSS SECTION SPECTRUM OF DIRECT REACTION FOR THE NEUTRONIC CALCULATION OF NEW GENERATION REACTOR. The demand on new spectrum of neutronic cross section comes from the Nuclear Energy System (NES) of new reaction generation since it could not be fulfilled anymore by the existing nuclear data. Neutron, uncharged particle, gives no magnetic interaction when it is passed onto a magnetic field, as the charged one does. Consequently, it is difficult to measure the neutronic spectrum with a good enough energy resolution. Taking advantage from the similarity of neutron and proton (spin and mass), it is possible to study the neutronic reaction using the analogue protonic one. In the current research, the general characteristics of cross section of nucleon is studied intensively as the most pronounced contribution in higher energy region. The cross section of nucleon is approached by the DWBA (Distorted Wave Born Approximation) theorem, and executed by the DWUCK4 code using global parameter of OMP (Optical Model Potential). The comparation between the calculation results and a data of reference, shows good agreement in the characteristics of all dominant single-states of nucleon.
