The bulk rotation velocity and surface envelope of a drifting unneutralized electron beam have been measured. These measurements verify various properties predicted by nonneutral-plasma theory. One unusual feature is that in some instances, the bulk rotation is opposite to the normally associated with the equilibria. Rotation at angular velocities greater than ω_c is also observed. In addition, the wavelength of the time-independent surface envelope is found to depend on the amount of ripple present.
