The thermal-to-epithermal neutron ratio (f) and epithermal neutron shaping factor (a) are essential parameters when calculating the concentration of samples using the k0-standardization method in the Large sample neutron activation analysis (LSNAA). The work was performed in a newly installed Large Sample Neutron Activation Analysis facility in the Ghana Research Reactor-1 (GHARR-1) facility using Au/Zr monitor couple. The thermal to epithermal neutron ratio was found to be 8.25 ± 0.14 and epithermal neutron shape factor (a) was also found to be 0.32998 ± 0.012. These results aided us in the determination of elemental concentration of “large samples†using the k0-standardization method at the GHARR-1 facility.References
