Tek Kütle Numaralı Deforme Çekirdeklerde Elektrik Dipol (E1) Titreşimlerinin Teorik Olarak Araştırılması

Bu çalışmada ilk kez, periyodik tablonun farklı kütle bölgelerinde yer alan tek-A’lı deforme çekirdeklerde gözlenen elektrik dipol uyarılmalarını (E1) teorik olarak açıklamak ve sistematik özelliklerini ortaya koymak amacıyla Öteleme ve Galileo Değişmez (TGI-) Kuaziparçacık Fonon Nükleer Model (QPNM) formüle edilerek FORTRAN programlama dilinde bilgisayar kodu yazılmıştır. Tek-A’lı çekirdeğin QPNM hamiltoniyenin ortalama alan yaklaşımı nedeniyle bozulan öteleme ve Galileo simetrisi Pyatov-Salamov restorasyon metodu yardımıyla onarılmıştır.

Formüle edilen TGI-QPNM ile düşük enerjili (2-4 MeV) dipol spektrumları deneysel olarak belirlenen 139La, 141Pr, 143Nd, 151,153Eu, 155,157Gd, 159Tb, 161,163Dy, 165Ho, 167Er, 169Tm, 181Ta, 175Lu, 235U ve 239Pu deforme çekirdeklerinde, bu enerji aralığındaki E1 uyarılmalarına ait ince yapı ve toplam özellikleri hesaplanmış, elde edilen sonuçlar deneysel verilerle karşılaştırılmıştır. Ayrıca farklı enerji bölgelerindeki (2-4 MeV, 4-10 MeV ve 10-20 MeV) E1 uyarılmalarının tek kütle numaralı çekirdeklerde sistematik özellikler sergileyip sergilemediğinin belirlenmesi için nadir toprak bölgesinde seçilen 133-141La, 153-159Eu, 151-161Gd, 155-165Dy, 155-169Ho, 157-167Er ve 167-179Lu izotop zincirleri ile aktinitler bölgesinde seçilen 229-233Th ve 233-239U izotop zincirleri için 2-20 MeV enerji aralığındaki E1 uyarılmalarına ait ince yapı ve toplam özellikleri ilk kez TGI-QPNM ile hesaplanmıştır.
