It is shown that the anomalous divergence of the supercurrent in a supersymmetric non-Abelian gauge theory may
be removed at the one-loop level by coupling three scalar multiplets in the adjoint representation to the supersym-
metric Yang-Millsmultiplet.
We recently demonstrated that an anomaly exists
[1] for the divergence of the supercurrent in a super-
symmetric non-Abelian gauge theory. The specific
model studied [2] consisted of a zero-mass Yang-Mills
multiplet interacting with a single massless Majorana'
spin 1/2 field transforming as the adjoint representa-
tion of the internal symmetry group, taken as SU(2)
for simplicity. In this case the supersymmetry Noether
current cJu is only formally conserved. An anomaly
exists, since the matrix element of cSu connecting the
vacuum to the one boson-one fermion state is not con-
