Coupled channel analysis indicates that an octupole vibration coupled to the quadrupole static deformation is sufficient to explain the inelastic excitation by proton scattering of the K ~r = 0-octupole band in lS2Sm. The isoscalar dipole degree of freedom is found not to be necessary, at least for this mass region, to explain the excitation of the 1-state of the octupole band.
