Generalized gauge-space rotations in atomic nuclei: A critical insight
Chong Qi, Roberto J. Liotta, Ramon Wyss
We critically reexamine the concepts of pairing rotations and moments of inertia in gauge space extracted from experimental binding energies. Our analysis focuses on pairing correl…
Three-Body Barrier Dynamics of Double-Alpha Decay in Heavy Nuclei
Shulin Tang, Tao Wan, Yibin Qian +6
The simultaneous emission of two particles--double- decay--represents a long-predicted but unobserved mode of nuclear radioactivity. Here we formulate this process as a genu…
Multistep shell model in the complex energy plane
Z. X. Xu, C. Qi, R. J. Liotta +1
We have adopted the multistep shell model in the complex energy plane to study nuclear excitations occurring in the continuum part of the spectrum. In this method one proceeds by s…
Competition of different coupling schemes in atomic nuclei
C. Qi, R. J. Liotta, R. Wyss
Shell model calculations reveal that the ground and low-lying yrast states of the nuclei Pd and Cd are mainly built upon isoscalar spin-aligned neutron-pro…
Coherence features of the spin-aligned neutron-proton pair coupling scheme
C. Qi, J. Blomqvist, T. Bäck +4
The seniority scheme has been shown to be extremely useful for the classification of nuclear states in semi-magic nuclei. The neutron-proton () correlation breaks the seniority…
Multistep shell model description of spin-aligned neutron-proton pair coupling
Z. X. Xu, C. Qi, J. Blomqvist +2
The recently proposed spin-aligned neutron-proton pair coupling scheme is studied within a non-orthogonal basis in term of the multistep shell model. This allows us to identify sim…
Spin-aligned neutron-proton pair mode in atomic nuclei
Chong Qi, J. Blomqvist, T. Bäck +4
Shell model calculations using realistic interactions reveal that the ground and low-lying yrast states of the nucleus Pd are mainly built upon isoscalar neutron-…
Calculation of the spectrum of 12Li by using the multistep shell model method in the complex energy plane
Z. X. Xu, R. J. Liotta, Chong Qi +4
The unbound nucleus Li is evaluated by using the multistep shell model in the complex energy plane assuming that the spectrum is determined by the motion of three neutrons o…
Pairing and continuum effects in nuclei close to the drip line
M. Grasso, N. Sandulescu, Nguyen Van Giai +1
The Hartree-Fock-Bogoliubov (HFB) equations in coordinate representation are solved exactly, i.e., with correct asymptotic boundary conditions for the continuous spectrum. The calc…
Resonant continuum in the Hartree-Fock+BCS approximation
N. Sandulescu, Nguyen Van Giai, R. J. Liotta
A method for incorporating the effect of the resonant continuum into Hartree-Fock+BCS equations is proposed. The method is applied for the case of a neutron-rich nucleus calculated…
Generalized seniority scheme in light Sn isotopes
N. Sandulescu, J. Blomqvist, T. Engeland +4
The yrast generalized seniority states are compared with the corresponding shell model states for the case of the Sn isotopes Sn. For most of the cases the energies agr…
Shell model on a random gaussian basis
K. Varga, R. J. Liotta
Pauli-projected random gaussians are used as a representation to solve the shell model equations. The elements of the representation are chosen by a variational procedure. This sch…
