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

In the present work, the intrinsic nuclear structures of the 180–190 W 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, γ - and 2 γ -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 180–190 W isotopes.
