Abstract
Improvements in neutron spectroscopy have made possible measurements of the spin-wave spectra for nickel over much of the zone for the [111] and [100] directions. Broadening of the spin-wave excitations has been directly observed for the [111] direction and the nature of the optical spin wave has been further characterized for the [100] direction. Comparison of the measured results is made with recent theoretical calculations.
