Effective mass of free neutrons in neutron star crust
, 2005 The inner layers of a neutron star crust, composed of a Coulomb lattice of neutron rich nuclear clusters immersed in a sea of ``free'' superfluid neutrons, are closely analogous to periodic condensed matter systems such as electronic, photonic or ...

Invariant Imbedding and Neutron Transport Theory III-Neutron-Neutron Collision Processes [PDF]
Indiana University Mathematics Journal, 1959 Abstract : The effects on criticality of neutron-neutron collisions involving annihilation are investigated for one-dimensional, single and multi-group cases. The analytic treatment shows that regardless of the magnitude of the cross section for collision between moving neutrons, there is no critical length (mass).

Isospin Diffusion in Heavy-Ion Collisions and the Neutron Skin Thickness of Lead
, 2005 The correlation between the thickness of the neutron skin in Pb-208, and the degree of isospin diffusion in heavy-ion collisions is examined. The same equation of state is used to compute the degree of isospin diffusion in an isospin-depedent transport ...
