ABSTRACT
Using Ngraph software, the parameters of various functions were determined by least squares analysis of fits to experimental efficiencies, εf of a coaxial HPGe detector for gamma rays in the energy range 59 keV to 1836 keV. When these parameters had been determined, their reliability was tested by the calculated goodness-of-fit parameter χ2cal It is shown that the function, where n = 3, gives satisfactory results.
ABSTRAK
Menggunakan perisian Ngraph, parameter pelbagai fungsi ditentukan dengan kaedah penyesuaian kuasa-dua terkecil untuk kecekapan ujikaji, εf dalam julat tenaga sinar gama 59 ke V ke 1836 ke V untuk satu pengesan HPGe sepaksi. Setelah parameter ini ditentukan, kebolehpercayaan yang fungsi, dimana n = 3 memberikan keputusan yang memuaskan.
