A method is developed for determining the inspection parameters of diesel fuels using gas chromatography. After one measurement which lasts on the order of 140 min, it is possible to determine the n–paraffin content, distillation curve, cetane numb

As a beam of precessing neutrons passes through nonmagnetic matter or the range of potential action, there appears an additional angle of precession. This phenomenon is due to a difference in the phase shifts for two spin components of the neutron wa

The authors examine in detail the effect of the gravitational field of the Earth and its rotation in the spin precession of neutrons moving in an external steady magnetic field. It is shown that the effect is significant for slow neutrons diffracting

It is shown that a spin-orbit interaction of neutrons with crystal nuclei leads to a new phenomenon: neutron spin precession in nonmagnetic unpolarized single crystals and spin dichroism. The spin of the diffracted neutrons with a wavelength of 0.15
