Abstract
A theoretical studying of nuclei in the shell
closure region (N =82), in particular cerium isotopes 136-138Ce, has
been made in the frame of macroscopic-microscopic, Cranked Nilsson Strutinsky
(CNS)model. Many nuclear properties have been calculated and discussed: the
single particle energy, the total energy, the liquid drop energy, the moments
of inertia, the deformation parameters, the nuclei shape, and potential energy surfaces (PES) have been
presented. High spin rotational bands of these isotopes have been
studied and interpreted based on fixed configurations in the frame of CNS code.
A good agreement is found with the observed results for these nuclei in the
recent works.

Abstract
Makroskopik-mikroskopik, Cranked Nilsson
Strutinsky (CNS) modeli çerçevesinde, kabuk kapanma bölgesinde (N = 82),
özellikle 136-138Ce seryum izotoplarında çekirdeklerin teorik bir incelemesi yapılmıştır.
Birçok nükleer özellik hesaplanmış ve tartışılmıştır: tek parçacık enerjisi,
toplam enerji, sıvı damlası enerjisi, eylemsizlik momentleri, deformasyon
parametreleri, çekirdek şekli ve potansiyel enerji yüzeyleri (PES) sunulmuştur.
Bu izotopların yüksek spin dönme bantları, CNS kodu çerçevesinde sabit
konfigürasyonlara dayalı olarak çalışılmış ve yorumlanmıştır. Son çalışmalarda
bu çekirdeklerin gözlenen sonuçları ile iyi bir uyum bulunmuştur.
