Evolution of intrinsic nuclear structure in medium mass even-even Xenon isotopes from a microscopic perspective *

Abstract

In this study, the multi-quasiparticle triaxial projected shell model (TPSM) is applied to investigate -vibrational bands in transitional nuclei of . We report that each triaxial intrinsic state has a -band built on it. The TPSM approach is evaluated by the comparison of TPSM results with available experimental data, which shows a satisfactory agreement. The energy ratios, B(E2) transition rates, and signature splitting of the -vibrational band are calculated.

Quasiparticle structure of low-lying yrast energy levels and $$\gamma $$-bands in $$^{164{-}174}$$Hf nuclei

“…The theoretical framework of the Triaxial Projected Shell Model is similar to the spherical shell model with only difference that the basis employed for diagonalizing the shell model Hamiltonian are triaxially deformed rather than the spherical one. The Hamiltonian employed in the present work is same as the one used in some earlier works [10,[27][28][29][30].…”

“…In the present work an attempt has been made to investigate nuclear structure properties indicating triaxiality in doubly even isotopic chain of Hafnium isotopes with A ranging from 164 to 174 by using the theoretical framework of Triaxial Projected Shell Model (TPSM). The TPSM has been proved to be very successful in some earlier research works on nuclei lying in the mass region A ≈ 120 [27][28][29] and on Er nuclei [10,30] with A ≈ 160 describing γ -vibrational bands. Hence the present work is taken up as a challenge for the successful application of TPSM on even-even 164−174 Hf isotopes.…”
