Abstract (data abstract)
FERMILAB-TEVATRON. Measurement of the inclusive differential cross sectionsD2SIG/DPT/DY in UPSILON(1S), UPSILON(2S) and UPSILON(3S) production in PBAR P c ollisions at centre-of-mass energy 1800 GeV. A study is also presented of the polarization through angular distribution measurements. The data were collected during the 1993-95 running period with an integrated luminosity of 77 +- 3 pb-1.
