THE log(ft) VALUES IN SPHERICAL AND DEFORMED NUCLEI FOR SOME ODD-A GERMANIUM ISOTOPES

Abstract

The log(ft) values of the allowed 𝛽± decay between odd-A spherical and deformed nuclei are studied for germanium isotopes in this paper. The Pyatov Method (PM) and the Schematic Model (SM)) are used to the GT strength distributions, including the schematic residual spin-isospin interaction between nucleons in the particle-hole and particle-particle channels. Particle-hole and particle-particle interaction parameters are calculated respectively with X_ph^GT= 5.2 A^(0.7 ) MeV and X_pp^GT= 0.58 A^(0.7 ) MeV. Deformed Woods-Saxon potential is used in calculations of single-particle energies and wave functions. The results are also compared with previous experiment values wherever available.

BAZI TEK ÇEKİRDEKLİ GERMANYUM İZOTOBU İÇİN DEFORME VE KÜRESEL ÇEKİRDEKLERİN LOG(FT) DEĞERLERİ

Abstract

Bu makalede germanyum izotopları için tek-A küresel ve deforme çekirdekler arasında izin verilen 𝛽± bozunmasının log(ft) değerleri incelenmiştir. Pyatov Metodu (PM) ve Şematik Model (SM)), parçacık-boşluk ve parçacık-parçacık kanallarındaki nükleonlar arasındaki şematik artık spin-izospin etkileşimi dahil olmak üzere GT şiddet dağılımları için kullanılmıştır. Parçacık-delik ve parçacık-parçacık etkileşim parametreleri sırasıyla X_ph^GT= 5.2 A^(0.7 ) MeV ve X_pp^GT= 0.58 A^(0.7 ) MeV ile hesaplanmıştır. Deforme olmuş Woods-Saxon potansiyeli, tek parçacık enerjilerinin ve dalga fonksiyonlarının hesaplanmasında kullanılmaktadır. Sonuçlar ayrıca, mümkün olan önceki deney değerleri ile karşılaştırılmıştır.
