MAGNETIC SCATTERING OF NEUTRONS.
Abstract
The present paper is the third in a series of annual reports describing the work on magnetic scattering of neutrons at Institutt for Atomenergi, Kjeller, Norway, performed under contract with the U. S. Department of the Army, through its European Research Office. Experiments were carried out with both polarized and unpolarized neutrons. A larger part of them were inelastic scattering experiments, making use of the socalled diffraction method. Of paramount importance to this method is the geometry of the scattering surfaces associated with the inelastic scattering process. A treatment in the density matrix formalism of the scattering of polarized neutrons is reviewed. Special attention is paid to the inelastic scattering by spin waves and by magnetovibrations. The correctness of the formulas derived was demonstrated in some experiments which are described. The problem of how to measure the transverse polarization component of neutrons was investigated theoretically and experimentally. The experiments do not present a complete solution to the problem, the results obtained so far, however, seem promising. (Author)
