Due to resonance that occur in the epithermal energy region of a reactor, the flux spectra in that region deviates strongly from the ideal I/E law to a I/E1+α with alpha as the correction factor. The factor has to be determined if zirconium as monitor pairs to determine the correction factor for inner irradiation channel 5 and outer irradiation channel 7 of the Ghana Miniature Neutron Source Reactor. The result obtained shows good agreement with the previously determined values for other channels of the same reactor.
