Nuclear Structure Properties of even-even Chromium Isotopes and the E ect of Deformation on Calculated Electron Capture Cross Sections
Jameel-Un Nabi, Mahmut Boyukata, Asim Ullah +1
In this study, we investigate the role of nuclear deformation on the calculated electron capture cross section (ECC) of even-even chromium (Cr) isotopes. We first determined the nu…
-decay of N=126 isotones for the r-process nucleosynthesis
Jameel-Un Nabi, Necla Cakmak, Asim Ullah +1
The -decay properties of nuclei with neutron number is investigated in this paper. Two different versions of the proton-neutron quasi particle random phase (pn-QRPA) m…
