N2  - We report on measurements of the ?(1S), ?(2S), and ?(3S) differential cross sections (d2?/dpTdy)|y|<0.4, as well as on the ?(1S) polarization in pp? collisions at ?s = 1.8TeV using a sample of 77±3pb-1 collected by the collider detector at Fermilab. The three resonances were reconstructed through the decay ???+?-. The measured angular distribution of the muons in the ?(1S) rest frame is consistent with unpolarized meson production.
