Description

The possibility of measuring nuclear spin waves (NSW) by inelastic neutron scattering is discussed. The differential cross section and scattered state polarization for the scattering of thermal neutrons from systems described by the Suhl-Nakamura Hamiltonian are developed in the Van Hove correlation function formalism; the relevant correlation functions for the Suhl-Nakamura system are computed. The implications of these calculations for the feasibility of detecting nuclear spin wave modes in neutron scattering experiments are discussed. (orig.)

Abstract (German)

Es wird die Moeglichkeit diskutiert, Kernspinwellen durch inelastische Neutronenstreuung zu messen. Der differentielle Wirkungsquerschnitt und die Polarisation des gestreuten Zustandes bei der Streuung von thermischen Neutronen an Systemen, die durch den Suhl-Nakamura Hamiltonian beschrieben werden, werden mit dem Van Hove Korrelationsfunktionsformalismus entwickelt; die fuer das Suhl-Nakamura-System relevanten Korrelationsfunktionen werden berechnet. Die Implikationen dieser Rechnungen fuer die Moeglichkeit, Kernspinwellen in Neutronenstreuexperimenten nachzuweisen, werden diskutiert. (orig.)
