Shield weight optimization using Monte Carlo transport calculations [PDF]

, 1971
Outlines are given of the theory used in FASTER-3 Monte Carlo computer program for the transport of neutrons and gamma rays in complex geometries. The code has the additional capability of calculating the minimum weight layered unit shield configuration ...

Neutron star crust beyond the Wigner-Seitz approximation

, 2007
For more than three decades, the inner crust of neutron stars, formed of a solid lattice of nuclear clusters coexisting with a gas of electrons and neutrons, has been traditionally studied in the Wigner-Seitz approximation.

Key Problems to Be Solved Possibly Using Machine Learning in Heavy Ion Collisions

Yuanzineng kexue jishu, 2023
Heavy-ion collisions provide a unique opportunity to study the nuclear equation of state for a wide range of densities, temperatures, and neutron-proton asymmetries in the laboratory.

Observation of a continuous phase transition in a shape-memory alloy

, 2008
Elastic neutron-scattering, inelastic x-ray scattering, specific-heat, and pressure-dependent electrical transport measurements have been made on single crystals of AuZn and Au_{0.52}Zn_{0.48} above and below their martensitic transition temperatures ...

Isospin splitting of the nucleon mean field

, 2005
The isospin splitting of the nucleon mean field is derived from the Brueckner theory extended to asymmetric nuclear matter. The Argonne V18 has been adopted as bare interaction in combination with a microscopic three body force.

Role of nucleon-nucleon correlation in transport coefficients and gravitational-wave-driven r-mode instability of neutron stars

Physics Letters B, 2020
The thermal conductivity and shear viscosity of dense nuclear matter, along with the corresponding shear viscosity timescale of canonical neutron stars (NSs), are investigated, where the effect of Fermi surface depletion (i.e., the Z-factor effect ...
