Study of Nuclear Structure of Neutron-Rich Even-Even Tungsten Nuclei Within Theoretical Framework

In the present work, the intrinsic nuclear structures of the W180-190 isotopes have been systematically investigated by employing the triaxial projected shell model within the deformed basis. The diagonalization of model Hamiltonian gives rise to yrast spectra, gamma- and 2 gamma-bands which successfully describe the intrinsic band structure of these tungsten isotopes. In addition, the role of the i(13/2) neutron orbitals of the intruder major shell N = 6 in explaining nuclear structure properties is also highlighted. Further, other nuclear structure properties like back-bending in moment of inertia, interband and intraband transition probabilities, wave-functions, nuclear g-factors, etc. have also been calculated and are compared with the known experimental data to get an in-depth understanding of the intrinsic nuclear structure of W180-190 isotopes.
