Deformed neutron halo nuclei and soft dipole excitations in the 40<A<90 mass region
Xiao Lu, Cong Pan, Hiroyuki Sagawa +2
We study deformed neutron halo nuclei in the mass region and their soft electric dipole () excitations based on the deformed relativistic Hartree-Bogoliubov theor…
The quenching of the axial-vector coupling constant in -decay: joint effects from chiral two-body currents and many-body correlations
Bin-Lei Wang, Wan-Li Lv, Li-Gang Cao +4
In nuclear -decay calculations, the axial-vector coupling constant usually needs to be quenched phenomenologically by a factor 0.75 to reproduce…
Novel microscopic approaches for Spin-Isospin excitations and Beta-decay
Hiroyuki Sagawa
We explore unsolved nuclear structure problems related with the spin and isospin degree of freedom by using microscopic models which accommodate realistic isoscalar and isovector p…
A Halo: The Trigger to a New Era of Nuclear Correlations
Hiroyuki Sagawa, Xiao Lu, Shan-Gui Zhou
In this contribution to the Halo-40 Proceedings, we discuss two topics regarding halo phenomena: The first is the pairing anti-halo effect on the neutron radius of halo nuclei and…
Octupole correlations in superdeformed bands of Ni
Xiao Lu, Shivani Jain, Hiroyuki Sagawa +1
The projected multi-dimensionally-constrained relativistic Hartree-Bogoliubov model was employed to calculate the potential energy surface of the high-spin states in $^{56}\text{Ni…
Dipole response of deformed halo nuclei Ne and Mg
Xiao Lu, Hiroyuki Sagawa, Shan-Gui Zhou
We study the soft electric dipole () response of deformed halo nuclei Ne and Mg using a deformed Woods-Saxon potential, with the potential depth adjusted to repro…
