Modulation of the neutron field in the multiplying condensed matter and coolant
Abstract
The spatial damping of acoustic, neutron and thermal branches of oscillations are found in neutron multiplying medium with coolant. All three branches give additive contribution to the neutron density oscillations. However, their wave numbers and coefficients of spatial damping (at the same frequency) differ greatly from the sound with its high phase velocity and small attenuation to the neutron wave with the damping length, which is comparable with its wavelength. A spatial growth of neutron density oscillations is found in the case of large frequency of neutron capture and weak coupling of neutron density and temperature branches of oscillations. This fact is of importance for the noise diagnostics of the multiplying medium with coolant. The results can be applied to the development of the methods of noise diagnostics of the in core reactor equipment.

Normal and pioncondensed states in neutron star matter in a relativistic field theory constrained by bulk nuclear properties
A theory of isospin asymmetric matter and of neutron star matter in particular, which is compatible with bulk nuclear properties, is formulated in the framework of a relativistic field theory and solved in the mean field approximation. The selfconsistent conditions defining the sigma/sup /, ..omega../sup /, ..pi../sup /, and rhofields are derived for the normal and the pioncondensed states in explicit form for asymmetric matter, which is in chemical equilibrium, and with prescribed total charge. 
Normal and pioncondensed states in neutron star matter in a relativistic field theory constrained by nuclear bulk properties, II
A relativistic field theory of isospin asymmetric matter and of neutron star matter in particular, which is compatible with nuclear matter bulk properties, was formulated in Part I of this series and treated in meanfield approximation. The selfconsistent solutions include the sigma, ..omega.., and rhofields for both the normal and pionconsensed states. The bulk properties of nuclear matter such as saturation density and energy, compressibility and asymmetry energy impose rather stringent restrictions on mesonnucleon coupling constants and the parameters of the nonlinear interactions in the sigmamodel. The numerical results include the equation of state, particle densities as functions of chargemore »
