Spin relaxation processes in superfluid /sup 3/He-A were investigated by the pulsed NMR methods. At low tilt angles the main relaxation process was that proposed by Leggett and Takagi. When the tilt angle was > or approx. =40/sup 0/, homogeneous spin precession was unstable and it split into large-amplitude spin waves. In this case the process of relaxation was governed by spin diffusion. A comparison was made of the experimental data with a theory of instability of homogeneous precession suggested by Fomin.
