A satellite peak has been observed in the NMR spectrum of rotating /sup 3/He-A; the peak intensity depends linearly on ..cap omega.. at the high angular velocities, ..cap omega.. = 0.6--1.5 rad/s, needed to resolve it. The frequency shift of the satellite is independent of ..cap omega... These results strongly suggest the existence of vortices in rotating /sup 3/He-A with the vortex density proportional to ..cap omega... Another satellite peak also has been observed which probably is due to solitons.
