Abstract
We report on the analysis of Charmonium and Bottomium states produced in p-Si interactions at root s = 38.7 GeV. The data have been collecte d with the open geometry spectrometer of the E771 Experiment at the FN AL High Intensity Lab. J/psi psi' and Y total cross sections as well a s the ratio B(psi' --> mu mu)sigma(psi)/(B(J/psi, --> mu mu)sigma(J/ps i)) have been measured. Results are compared with theoretical predicti ons and with results at other energies.
