Abstract

Reaction
cross section refers to the probability of a nuclear reaction’s occurrence.
In
addition, a wide range of reaction area data is used.
This working cross sections of the 13C(α,n) 16O reaction
have been evaluated at 0-8 MeV energy area. In these hypothtetical evaluated,
the TALYS 1.8 the codes have been used. Moreover the Astrophysical S-factors that
explain the probability of reaction in flow energy were evaluated. Conclusions
of our calculations were control off the experimental data obtained from EXFOR
 database. The root of the chemical elements
has been issue of numerical studies since current physics was born. Decades,
its examination has drawn the attention of cosmologists, astrophysicists, and
astronomers, furthermore empirical, theoretical particle, and nuclear
physicists. The
13C (α,n)16O
reaction is the neutron origin for the major component of the
s-process,
in charge of for the production process of plenty of the nuclei in the mass
range 90 <
A <208.  In particular, it is important to know the
variation in the region of low energies in order to test the accuracy of the
model calculations.

Abstract

Reaksiyon tesir kesiti bir nükleer reaksiyonun gerçekleşme olasılığını ifade eder. Ayrıca Reaksiyon tesir kesiti verileri çok geniş bir alanda kullanılmaktadır. Bu çalışmada, 13C(α,n) 16O reaksiyonunun kesitlerini, 0-8 MeV enerji  aralığında  hesap edilmiştir. Bu teorik hesaplarda, TALYS 1.8 kodları kullanıldı. Ayrıca düşük enerjilerde reaksiyon olasılığını açıklayan Astrofiziksel S-faktörleri hesaplanmıştır. Hesaplamalarımızın sonuçları, EXFOR veri tabanından elde edilen deneysel veriler açısından kontrol edildi. Kimyasal elementlerin kökeni, modern fiziğin doğmasından bu yana nicel çalışmalara konu olmuştur,  On yıllar boyunca, deneysel araştırmacıların, teorik parçacık ve nükleer fizikçilerin yanı sıra kozmologların, astrofizikçilerin ve astronomların ilgisini çekmiştir. 13C(α,n) 16O reaksiyonu, s-sürecinin ana bileşeni olarak 90<A<208 kütle aralığındaki çoğu çekirdeğin üretim sürecinden sorumlu olan nötron kaynağıdır. Özellikle model hesaplamalarının doğruluğunun test edilmesi için düşük enerji bölgesindeki değişimin bilinmesi önemlidir.
