THE TRANSITION PROBABILITIES OF 126-136 Ce ,132-138 Nd ve 134-140 Sm ISOTOPES IN THE RARE-EARTH REGION

Year 2016, Issue: 036, 55 - 62, 15.06.2016

Abstract

B(E2) transition probabilities for 126-136 Ce , 132-138 Nd and 134-140 Sm isotopes in the rare-earth region are calculated within Interaction Boson Model-2 (IBM-2) in which neutron and proton bosons are considered explicitly by NPBOS. These calculated values for B(E2) transition probabilities are compared with experimental ones. It is seen that calculated B(E2) transition probabilities are good agreement with the experimental ones.

Year 2016, Issue: 036, 55 - 62, 15.06.2016

Abstract

Nadir toprak elementleri bölgesinde bulunan 126-136 Ce , 132-138 Nd ve 134-140 Sm izotoplarının B(E2) geçiş olasılıkları, nötron ve proton bozonlarının farklı olarak ele alındığı Etkileşen Bozon Modeli–2 (IBM-2) çerçevesinde, NPBOS programı kullanılarak hesaplandı. Hesaplanan değerler deneysel verilerle karşılaştırıldı. Hesaplanan B(E2) geçiş olasılıklarının deneysel verilerle oldukça uyumlu sonuçlar verdiği görüldü.
