A simple approach to -decay fine structure
D. S. Delion, Monika Patial, R. J. Liotta +1
We propose a simple method to evaluate -transition rates to low-lying excited states in even-even nuclei. For this a realistic -daughter double folding interaction is approxi…
Empirical pairing gaps, shell effects, and di-neutron spatial correlation in neutron-rich nuclei
S. A. Changizi, Chong Qi, R. Wyss
The empirical pairing gaps derived from four different odd-even mass staggering formulas are compared. By performing single- shell and multi-shell seniority model calculations a…
Shape coexistence and triaxiality in nuclei near 80Zr
S. J. Zheng, F. R. Xu, S. F. Shen +2
Total-Routhian-Surface calculations have been performed to investigate the shape evolutions of nuclei, Zr, Sr and Mo. Shape coexistences of…
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…
Microscopic-Macroscopic Approach for Binding Energies with Wigner-Kirkwood Method
A. Bhagwat, X. Viñas, M. Centelles +2
The semi-classical Wigner-Kirkwood expansion method is used to calculate shell corrections for spherical and deformed nuclei. The expansion is carried out up to fourth orde…
Critical Survey of Isoscalar and Isovector Contributions to the Spin Orbit Potential in Relativistic Mean Field Theory
A. Bhagwat, R. Wyss, W. Satula +2
The spin-orbit (SO) interaction, emerging naturally from the Relativistic Mean Field (RMF) theory is examined critically in the light of the recently measured excitation energy dif…
Enhanced Stability of Superheavy Nuclei due to High-Spin Isomerism
F. R. Xu, E. G. Zhao, R. Wyss +1
Configuration-constrained calculations of potential-energy surfaces in even-even superheavy nuclei reveal systematically the existence at low excitation energies of multi-quasipart…
Cranking in Isospace
S. Glowacz, W. Satula, R. Wyss
The response of isovector and isoscalar pairing to generalized rotation in isospace is studied. Analytical expressions for non-selfconsistent solutions for different limiting cases…
Comments on the nuclear symmetry energy
W. Satula, R. Wyss
According to standard textbooks, the nuclear symmetry energy originates from the {\it kinetic} energy and the {\it interaction} itself. We argue that this view requires certain mod…
Microscopic structure of fundamental excitations in N=Z nuclei
Wojciech Satula, Ramon Wyss
Excitation energies of the =1 states in even-even as well as =0 and =1 states in odd-odd = nuclei are calculated within the mean-field approach. It is shown that the…
Rotations in isospace: a doorway to the understanding of neutron-proton superfluidity in N=Z nuclei
W. Satuła, R. Wyss
The =2 excitations in even-even = nuclei are calculated within the isospin cranked mean-field approach. The response of pairing correlations to rotation in isospace is inv…
A number projected model with generalized pairing interaction
W. Satula, R. Wyss
A mean-field model with a generalized pairing interaction that accounts for neutron-proton pairing is presented. Both the BCS as well as number-projected solutions of the model are…
Quadrupole Pairing Interaction and Signature Inversion
F. R. Xu, W. Satula, R. Wyss
The signature inversion in the πh11/2 \otimes νh11/2 rotational bands of odd-odd Cs and La isotopes and the πh11/2 \otimes νi13/2 bands of odd-odd Tb, Ho and Tm nuclei is investiga…
Onset of T=0 Pairing and Deformations in High Spin States of the N=Z Nucleus 48Cr
J. Terasaki, R. Wyss, P. -H. Heenen
The yrast line of the N=Z nucleus 48Cr is studied up to high spins by means of the cranked Hartree-Fock-Bogoliubov method including the T=0 and T=1 isospin pairing channels. A Skyr…
Competition Between T=0 and T=1 Pairing in Proton-Rich Nuclei
W. Satuła, R. Wyss
A cranked mean-field model with two-body T=1 and T=0 pairing interactions is presented. Approximate projection onto good particle-number is enforced via an extended Lipkin-Nogami s…
