Abstract

This paper deals with a measured gamma-ray spectrum and designing a MATLAB program to perform

peak finding procedure by using the differences of the experimental data as well as performing fitting

process by using Newton-Gauss least square technique. Then, five different methods of peak area

determination are proposed to analyze the symmetry lines of Po212 in the spectrum, and the comparison

was done using the percentage variance reduction test.

Keywords: Nuclear physics, Gamma ray spectrum, Peak area determination.
