Nuclei Shapes across Different Magic Numbers in the Ytterbium (Z = 70) and Lead (Z = 82) Isotopes using MATLAB Code.

The yrast state of the Ytterbium, Yb isotopes for the neutron range of 82 ≤ N≤ 180 and lead, Pb isotopes for the neutron range of 98 ≤ N≤132 for the even-even nuclei have been studied using the energies of the first excited state in these nuclei. The nuclear deformation parameters, and the reduced quadruple transition probability B (E2)↑ with other intrinsic parameters associated with the nuclei shape were obtained using a MATLAB code. The results revealed that the Pb nucleus with Z = 82 - which is one of the magic numbers have a more ‘spherically’ nuclei shape at the ground state with small degree of deformation as compared to the nuclei shapes in the Yb isotopes. Our study supports the global predictions of the prolate deformation in Yb isotopes around the neutron range of 90 ≤ N ≤ 112.

YRAST STATES IN 188,190Os NUCLEI

Yrast states in neutron rich nuclei 188 Os and 190 Os have been populated using the deep-inelastic reaction 82 Se + 192 Os at 460 MeV beam bombarding energy. A thick 192 Os target (>50 mg/cm 2) with 0.2 mm Ta backing was used to stop all of the recoils in the target, minimising the broadening of the lines due to Doppler shift. High fold γ-γ coincidences were aquired with the 4π spectrometer GASP detector array. Three and two dimensional gamma-ray matrices were used to construct level schemes of the nuclei of interest up to an yrast state of 22.
