The heat kernel for the spin-3/2 Rarita-Schwinger gauge field on an arbitrary
Ricci flat space-time (d>2) is investigated in a family of covariant gauges
with one gauge parameter α. The α-dependent term of the kernel is
expressed by the spin-1/2 heat kernel. It is shown that the axial anomaly and
the one-loop divegence of the action are α-independent, and that the
conformal anomaly has an α-dependent total derivative term in
d=2m≥6 dimensions.Comment: 11 pages, latex, ITP-SB-94-3
