Time-reversal invariance and charge symmetry have been studied in polarization measurements of single-nucleon transfer reactions in the mass five system. First, we experimentally established the equality of the proton analyzing power, A, for /sup 4/He(p,d)/sup 3/He at 32 MeV and the polarization, P, of the inverse reaction, thereby checking time-reversal invariance. Then in a double scattering experiment using the reactions /sup 3/H(d,n)/sup 4/He and /sup 4/He(n,d)/sup 3/H at theta/sub c.m./ = 38.6/sup 0/ and assuming P = A (from time-reversal invariance) we obtained a polarization of 0.480 +- 0.016 for the 50 MeV neutrons. When this value is used, good agreement is found between the analyzing power distributions of /sup 4/He(n,d)/sup 3/H and /sup 4/He(p,d)/sup 3/He at 50 MeV, which is consistent with charge symmetry.
