CALCULATION OF QUADRUPOLE DEFORMATION PARAMETER β2 FROM REDUCED TRANSITION PROBABILITY B(E2)↑ FOR 01+ → 21+ TRANSITION AT EVEN-EVEN 62-68Zn ISOTOPES

In this work the excited energy levels, reduced transition probabilities B(E2)up arrow, intrinsic quadrupole moments, and deformation parameters have been calculated for( 62-68)Zn isotopes with neutrons number N = 32, 34, 36 and 38. NuSheIIX code has been applied for all energy states of fp-shell nuclei. Shell-model calculations for the zinc isotopes have been carried out with active particles distributed in the lp(3/2), 0f(5/2), and lp(1/2) orbits outside doubly magic closed Ni-56 core nucleus. By using f5p model space and f5pvh interaction, the theoretical results have been obtained and compared with the available experimental results. The excited energies values, electric transition probability B(E2), intrinsic quadrupole moment Q(0), and deformation parameters beta(2) have appeared in complete agreement with the experimental values. As well as, the energy levels have been confirmed and determined for the angular momentum and parity of experimental values that have not been well established and determined experimentally. On the other hand, it has been predicted some of the new energy levels and electric transition probabilities for the Zn62-68 isotopes under this study which were previously unknown in experimental information.
