A special type of neutron-proton pairing interaction and the moments of inertia of some deformed even-even nuclei in the rare earth region

Guliyev, Ali (IOP PUBLISHING LTD, 1998)

In this work, the effect of a special type of neutron-proton pairing interaction on the moments of inertia of some deformed nuclei in the rare earth region is investigated. First, making a perturbative approximation, we ...
Change of the dipole strength distributions between the neighbouring gamma-soft nuclei Pt-194 and Pt-196

Guliyev, Ali (ELSEVIER SCIENCE BV, 2003)

A nuclear resonance fluorescence experiment with two highly efficient EUROBALL Cluster detectors has been performed on the gamma-soft nucleus Pt-194. Dipole excitations were observed between 2 and 4 MeV excitation energy. ...

In this study, the result of calculations using rotational, translational and Galilean invariant quasiparticle random-phase approximation is presented for the low-lying dipole excitations in the even-even (160)Gd nucleus. ...
Fully renormalized quasi-particle random phase approximation, spurious states and ground state correlations

Guliyev, Ali; Güner, Mehmet (IOP PUBLISHING LTD, 2004)

An approach, called fully renormalized QRPA (FR-QRPA), which takes into account the Pauli principle for the ground state correlations (GSC) and fulfills the Ikeda sum rule has recently been developed. Here a new rotational ...
Intrinsic g(K) factors of odd-mass Lu167-179 isotopes
