İki Ayırma Spektrometrelerinin Karşılaştırılması

137Cs gama enerji spektrumunda düşük enerji bölgesinin ayırımı için iki spektrometre incelenmiştir. Spektrometrelerden elde edilen spektrumlar birbiriyle karşılaştırılmıştır. Tam bir karşılaştırma yapmak için, kısmi ve bütün ayırma işlemleri gerçekleştirilmiştir.

A Comparison of Two Discrimination Spectrometers

Two spectrometers were examined for the discrimination of the low-energy part of the 137Cs gamma-ray spectrum. Obtained spectra from the spectrometers were compared with each other. To perform an exact comparison, partial and complete discrimination processes were realized.
