✦ Synopsis

The structure of the quasielastic incoherent neutron scattering from polydimethyl siloxane has been determined at low momentum transfer under conditions of high resolution.

Within the limits of experimental error the quasielastic peak is a single component; a two component peak was not found. The findings are consistent with a previous tentative interpretation of the quasielastic peak being due to a Doppler broadening phenomenon attributed to the long range conformational changes of the polymer backbone.
