Abstract

There are seventeen rare earth elements in the periodic table and fifteen of them are in the group of lanthanides. The other two are scandium and yttrium. In this work, cross section of photonuclear reaction of samarium isotope, which is in the light group of rare earth elements divided into two groups as light and heavy, are calculated. The calculations are performed by using different nuclear level density models (BSFGM, CTM, GSM, CSCFGM) with TALYS 1.95 computer program. The obtained results are compared with experimental data taken from EXFOR experimental data base. When the results are examined, it has been shown that collective semi-classical Fermi gas model (CSCFGM) is more successful in predicting and explaining the experimental data and can be safely used in cross section calculations of photonuclear reactions of rare earth elements.

Özet

Periyodik tabloda on yedi adet nadir toprak elementi bulunur ve bunlardan on beş tanesi lantanitler grubunda yer alır. Diğer iki tanesi ise skandinyum ve itriyumdur. Bu çalışmada, hafif ve ağır olarak iki gruba ayrılan nadir toprak elementlerinden hafif grubuna dahil olan samaryum izotopunun fotonükleer reaksiyonuna ait tesir kesiti değerleri hesaplanmıştır. Hesaplamalar, farklı nükleer seviye yoğunluğu modelleri (Geri-kaydırılmış Fermi gaz modeli-BSFGM, Sabit sıcaklık modeli- CTM, Genelleştirilmiş süperakışkan modelGSM, Kollektif yarı-klasik Fermi gaz modeli-CSCFGM) kullanılarak TALYS 1.95 bilgisayar programı ile yapılmıştır. Elde edilen sonuçlar EXFOR (Uluslararası Nükleer Veri Merkezi) deneysel veri tabanından alınan deneysel veriler ile karşılaştırılmıştır. Sonuçlar incelendiğinde, kollektif yarı-klasik Fermi gaz modelinin (CSCFGM) deneysel verileri tahmin etmede ve açıklamada daha başarılı olduğu ve nadir toprak elementlerinin fotonükleer reaksiyonlarının tesir kesiti hesaplamalarında güvenle kullanılabileceği gösterilmiştir.
