Isospin mixing and Fermi transitions for some deformed nuclei

Abstract: We have tried to give a self-consistent explanation of isospin mixing and Fermi beta decays for 54 ≤ Z ≤ 68 deformed nuclei. The effect of isospin impurity in nuclear ground states on Fermi beta transitions has been investigated considering the restoration of symmetry violations stemming from the mean field approximation. The isobar analogue excitations in neighbor odd-odd nuclei have been obtained by following the proton-neutron quasiparticle random phase approximation (pnQRPA) procedure. The dependence of is… Show more

“…This is indeed predicted by theoretical calculations [45] where total GT − is obtained as 72.12 and total GT + as 0.51. Also the Fermi strength of 24.0 goes to the IAS in 132 Cs at an excitation of ∼ 13.8 MeV [53]. Finally, the one and two neutron emission thresholds for the nucleus 132 Cs are at 7.17 and 16.40 MeV, respectively.…”
