We investigate the quasiparticle bands for a t-J bilayer within self-c
onsistent Born approximation. The antiferromagnetic fluctuations favor
d(x2-y2) wave superconductivity for a bilayer. One observes the incre
ment similar to 10K of T-c(max) with the growth from one plane to a bi
layer when the hole pairing induced by the spin-wave exchange is inclu
ded.
