Neutron rich nuclei and neutron stars [PDF]

open access: yesFission and Properties of Neutron-Rich Nuclei, 2013
The PREX experiment at Jefferson Laboratory measures the neutron radius of 208Pb with parity violating electron scattering in a way that is free from most strong interaction uncertainties. The 208Pb radius has important implications for neutron rich matter and the structure of neutron stars.

Neutron-Neutron Fusion [PDF]

open access: yesPhysics Letters B, 2005
The neutron-neutron fusion process, $nn\to de\nu$, at very low neutron energies is studied in the framework of pionless effective field theory that incorporates dibaryon fields.

An improved method for estimating the neutron background in measurements of neutron capture reactions [PDF]

open access: yesNuclear Instruments and Methods in Physics Research A 826 (2016) 80-89, 2016
The relation between the neutron background in neutron capture measurements and the neutron sensitivity related to the experimental setup is examined. It is pointed out that a proper estimate of the neutron background may only be obtained by means of dedicated simulations taking into account the full framework of the neutron-induced reactions and their

Particles in classically forbidden area, neutron skin and halo, and pure neutron matter in Ca isotopes [PDF]

open access: yesPhys.Rev. C61 (2000) 047302, 2000
The nucleon density distributions and the thickness of pure neutron matter in Ca isotopes were systematically studied using the Skyrme-Hartree-Fock model (SHF) from the $\beta$-stability line to the neutron drip-line. The pure neutron matter, related with the neutron skin or halo, was shown to depend not only on the Fermi levels of the neutrons but ...

Neutron Skins and Neutron Stars [PDF]

open access: yesAIP Conference Proceedings, 2013
The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

Neutron-mirror neutron mixing and neutron stars [PDF]

open access: yesThe European Physical Journal C, 2021
AbstractThe oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark stars $$n-n'$$

DEVELOPMENT OF NEURAL THERMAL SCATTERING (NeTS) MODULES FOR REACTOR MULTI-PHYSICS SIMULATIONS [PDF]

open access: yesEPJ Web of Conferences, 2021
Modern multi-physics codes, often employed in the simulation and development of thermal nuclear systems, depend heavily on thermal neutron interaction data to determine the space-time distribution of fission events.

Multi-messenger Observations of a Binary Neutron Star Merger [PDF]

open access: yesProceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors.
