Effective and efficient algorithm for the Wigner rotation matrix at high angular momenta

Bin-Lei Wang et al.

Summary: The Wigner rotation matrix, an important part of angular-momentum-projection operator in nuclear-structure models, suffers from numerical errors and instability. This paper proposes an effective and efficient algorithm based on Jacobi polynomials, which provides stable and high-precision results similar to the Fourier method.

Effect of nuclear deformation on the observation of a low-energy super-Gamow-Teller state

Cui-Juan Lv et al.

Summary: A well-known structure in nuclear excitation is the Gamow-Teller resonance, where concentrated Gamow-Teller transitions occur at higher-energy regions. The low-energy super-GT (LeSGT) state, which is the lowest J(pi) = 1(+) GT state, can also show concentrated GT strength under specific conditions. This phenomenon is observed when the initial and final nuclei have LS-closed-shell core structures and the core nuclei belong to certain shell closures.

Pfaffian formulation for matrix elements of three-body operators in multiple quasiparticle configurations

Zi-Rui Chen et al.

Summary: A Pfaffian formula is proposed to calculate matrix elements of three-body operators in symmetry-restoration beyond-mean-field methods, including multiple qp configurations. Numerical checks show that the efficiency of the new formula is about five times higher than the conventional method when considering four or fewer qp operators.

Urca Cooling in Neutron Star Crusts and Oceans: Effects of Nuclear Excitations

Long-Jun Wang et al.

Summary: The study investigates the influence of nuclear excitations on Urca cooling in the crust and ocean of neutron stars, providing an expression for Urca process neutrino luminosity and calculating the neutrino luminosities of candidate Urca cooling pairs with state-of-the-art nuclear structure inputs. The results show that nuclear excitations can significantly enhance total Urca neutrino luminosities in the accreted neutron star crust, potentially causing significant observational effects.

Origin of the heaviest elements: The rapid neutron-capture process

John J. Cowan et al.

Summary: The rapid neutron-capture process (r-process) is responsible for about half of the heavy elements found in nature, but uncertainties and open questions remain. Studies suggest that the production of the majority of heavy r-process elements may be associated with neutron-rich conditions, such as neutron star mergers.

Sensitivity of Neutron-Rich Nuclear Isomer Behavior to Uncertainties in Direct Transitions

G. Wendell Misch et al.

Summary: Nuclear isomers are excited in the rapid neutron capture process of nucleosynthesis, forming astromers. Astromers react and decay at different rates, requiring separate treatment in simulations. Transition rates and thermalization temperatures are determined by direct transitions, and unknown transitions impact astromer behavior.

Three-quasiparticle isomers in odd-even 159'161Pm: Calling for modified spin-orbit interaction for the neutron-rich region

R. Yokoyama et al.

Summary: Neutron-rich Pm isotopes were studied by delayed gamma-ray spectroscopy, revealing isomeric gamma decays with distinct quasiparticle excitations. A projected shell model calculation highlighted the importance of modifying Nilsson parameters to understand the properties of neutron-rich rare-earth nuclei around A = 165. This study also provided new evidence supporting the existence of the deformed N = 98 subshell gap in odd-mass nuclei.

Astromers: Nuclear Isomers in Astrophysics*

G. Wendell Misch et al.

Summary: The study develops a method to calculate transition rates between the ground state and long-lived isomers in nuclei, establishing criteria for determining when a nucleus should be considered a single species or two separate species based on a thermalization temperature. It is found that when destruction rates dominate and differ greatly, nuclear levels may not reach thermal equilibrium, impacting the distribution of occupation probability and nuclear reaction rate calculations. In such cases, isomers of astrophysical interest should be treated as separate species in nucleosynthesis networks.
