A novel projected shell model method for nuclear level density
Yang Sun, Jiaqi Wang, Saumi Dutta +1
We introduce a shell model method for calculating nuclear level density (NLD) generally applicable for arbitrarily heavy deformed nuclei. The method is novel because of our use of…
Projected shell model description of nuclear level density: Collective, pair-breaking, and multiquasiparticle regimes in even-even nuclei
Jiaqi Wang, Saumi Dutta, Long-Jun Wang +1
There is overwhelmingly experimental evidence indicating that excited nuclear states are dominated by quasiparticle (qp) excitations, which form many-body configurations with broke…
Nuclear level density studied in odd-mass nuclei in the framework of the projected shell model
Jiaqi Wang, Saumi Dutta, Cui-Juan Lv +2
In a recent article [Phys. Rev. C 108, 034309 (2023)], we proposed a projected shell model method for the calculation of nuclear level density (NLD) in deformed even-even nuclei. T…
Systematic study of the half-lives of nuclear bound-state decay
Jing-Wen Ran, Long-Jun Wang
Nuclear bound-state decay ( decay) is a novel weak-interaction process that becomes possible when atoms are highly ionized, such as in stellar environments or he…
Nuclear matrix element of decay of Ge: roles of high-lying states and two-body currents
Hua-Yang Xu, Hao Zhou, Long-Jun Wang
We present a microscopic analysis of the nuclear matrix element (NME) of the two-neutrino double- () decay for open-shell heavy deformed nuclei, taking into account the fa…
Effective -decay rates of -process waiting points in realistic stellar environments
Qi-Ye Hu, Long-Jun Wang, Yang Sun
Reliable nuclear weak rates are key inputs for understanding the origin of heavy elements and constraining the environments of the corresponding stellar nucleosynthesis. We present…
Many-body correlations as the origin of Gamow-Teller quenching in nuclear -decay
Hao Zhou, Long-Jun Wang, Yang Sun
The longstanding quenching problem of Gamow-Teller (GT) strength in nuclear -decay is attributed to missing contributions in the transition operator and/or incomplete nuclear co…
Stellar weak rates of the -process waiting points: Effects of strong magnetic fields
Qi-Ye Hu, Long-Jun Wang, Yang Sun
Incorporating microscopic nuclear-structure information into the discussion of bulk properties of astronomical objects such as neutron stars has always been a challenging issue in…
Nuclear spectrum from projected shell model (I): allowed one-to-one transition
Fan Gao, Zi-Rui Chen, Long-Jun Wang
Nuclear spectrum and the corresponding (anti-)neutrino spectrum play important roles in many aspects of nuclear astrophysics, particle physics, nuclear industry and nuclear dat…
Stellar weak-interaction rates for -process waiting-point nuclei from projected shell model
Zi-Rui Chen, Long-Jun Wang
We propose a projected shell model (PSM) for description of stellar weak-interaction rates between even-even and odd-odd nuclei with extended configuration space where up to six-qu…
An effective and efficient algorithm for the Wigner rotation matrix at high angular momenta
Bin-Lei Wang, Fan Gao, Long-Jun Wang +1
The Wigner rotation matrix (-function), which appears as a part of the angular-momentum-projection operator, plays a crucial role in modern nuclear-structure models. However, it…

Long-Jun Wang, Liang Tan, Zhipan Li +2
Capture of electrons by nuclei is an important process in stellar environments where excited nuclear states are thermally populated. However, accurate treatment for excited configu…
