A　scheme　is　presented　for　the　generation　of　superpositions　of　two　two-mode　SU(2)　coherent　states　of　the　motion　for　a　trapped　ion.　In　the　scheme　an　ion　is　trapped　in　a　two-dimensional　isotropic　harmonic　potential　and　driven　by　two　resonant　laser　beams.　Under　certain　conditions,　the　motional　two-mode　SU(2)　cat　state　can　be　generated　after　a　conditional　measurement　on　the　internal　state　following　the　ion-laser　interaction.
