| Abstract: | An approach of
neutron spectrum unfolding based on a stochastic evolutionary search mechanism
- Genetic Algorithm is presented. A pulse height spectrum at zero degree from
the nuclear reaction of incident energetic carbon ions on a thick silver target
carried out at an accelerator facility is used for the unfolding. The problem
is also converted to an under-determined one and is unfolded by the present
approach and the output is compared with results from the standard FERDOR code.
Necessity of carrying out smoothening of the obtained solution is also studied,
which leads to approximation of the solution yielding an appropriate solution
finally. A simple smoothening and a Monte Carlo averaging, based smoothening
methods have been studied. Unfolded flux value obtained after inclusion of the
smoothening criteria results in a close agreement to the output obtained from
the FERDOR code. |
