Abstract

In this work, the qualitative analysis has been performed by using ratio of coherent to backscattering intensity ratios. The samples in the mean atomic number range 4.268 <=(Z) over bar <= 5.786 and 9.743 <=(Z) over bar <= 83.00 were prepared by using dilution technique. 59.54 and 661.62 keV photon energies are obtained from the radioactive point sources of Am-241 and Cs-137 an activity of 0.43-0.20 MBq, respectively. The scattered gamma rays were counted by a HPGe detector with a resolution of 182 eV at 5.9 keV. The obtained intensity ratios are plotted as function of the mean atomic number and constituted a best-fit-curve. The correlation coefficients for the prepared samples in the mean atomic number range 4.268 <=(Z) over bar <= 5.786 are 0.976 and 0.970 at 59.54 and 661.62 keV photons, respectively. The correlation coefficients for the prepared samples in the mean atomic number range 9.743 <=(Z) over bar <= 83.00 are 0.964 and 0.967 at 59.54 and 661.62 keV photons, respectively. It is observed that there was a high correlation between coherent to backscattering intensity ratio and the mean atomic numbers. It was concluded that the recommended intensity ratio can be used for qualitative analysis.
