Neutron energy dependence of delayed neutron yields and its assessments

Dependence on neutron energy of the OER and RBE.

Neutron – Mirror Neutron Oscillation and Ultra High Energy Cosmic Rays

We discuss the phenomenological and astrophysical implications of neutron mirror neutron oscillation and show that the present experimental data allow an oscillation time in vacuum, τnn′ , much smaller than the neutron lifetime. Such a fast oscillation could provide a very efficient mechanism for transporting protons with super-GZK energies at very large distances provided that the CMB of mirro...

Symmetry energy , neutron star crust and neutron skin thickness ⋆

We analyze the correlations of the slope and curvature parameters of the symmetry energy with the neutron skin thickness of neutron-rich isotopes, and the crust-core transition density in neutron stars. The results are obtained within the microscopic Brueckner–Hartree–Fock approach, and are compared with those obtained with several Skyrme and relativistic mean field models.

Neutron fluctuations: The importance of being delayed.

The neutron population in a nuclear reactor is subject to fluctuations in time and in space due to the competition of diffusion by scattering, births by fission events, and deaths by absorptions. As such, fission chains provide a prototype model for the study of spatial clustering phenomena. In order for the reactor to be operated in stationary conditions at the critical point, the population o...

Estimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user

Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
