Kurşun İzotoplarının Toplam Fotonötron Tesir Kesiti

Radyasyonun geniş bir uygulama alanı bulunmasına rağmen yüksek dozda alınması sağlık açısından zararlı olduğundan radyasyondan korunma son yıllarda fiziğin önemli bir çalışma konusudur. Radyasyondan korunmada zırh malzemesi seçiminde radyasyonun madde ile etkileşiminin bilinmesi önemlidir. Bu anlamda zırh malzemesi olarak seçilecek malzemenin toplam tesir kesitinin bilinmesi gerekir. Bu çalışmada radyasyon zırhlamasında kullanılan en önemli malzeme olan kurşun ve izotoplarında fotonötron reaksiyon tesir kesitleri hesaplanmıştır. Hesaplamalarda TALYS-1.2 bilgisayar programı kullanılmıştır. Hesaplanan tesir kesitleri ile deneysel (EXFOR) ve değerlendirilmiş (TENDL) tesir kesitleri karşılaştırılmıştır. Hesaplanan tesir kesitleri ile literatürden edilen deneysel ve değerlendirilmiş tesir kesitlerinin birbirleriyle uyumlu olduğu görülmüştür.

The Total Photoneutron Cross Section of Lead Isotopes

Taking high doses of radiation, although there are a wide range of applications that are harmful to health, radiation protection is an important study of physics in recent years. The selection of armor material for radiation protection is important to know the interaction of radiation with matter. In this sense, the total cross section of the material to be chosen as the armor material must be known. In this study, photoneutron reaction cross sections are calculated for lead and isotopes that the most important materials used in radiation armored. TALYS 1.2 computer programme is used for calculated cross sections. The calculated cross sections have been compared with the experimental (EXFOR-Experimental Nuclear Reaction Data) and evaluated (TENDL- TALYS based Evaluated Nuclear Data Library) cross sections. It was seen that the agreement between all results, calculated cross section with experimental and evaluated cross sections, are good
