Available in PDF, EPUB and Kindle. Book excerpt: The program of physics analysis using CLEO II data is reported. A statistically significant measurement was made of the isospin mass splitting of the [Sigma][sub c][sup +] with respect to the [Sigma][sub c][sup o] and [Sigma][sub c][sup ++]. This result is based on first observation of the [Sigma][sub c][sup +] in the decay mode [Lambda][sub c][sup +][pi][sup 0]. Many new decay modes of the charmed baryon [Lambda][sub c][sup +] were studied. Several new decay modes of [xi][sub c]'s. Some preliminary results on 3 new modes of [Omega][sub c][sup 0] decay are reported. In the area of B-meson decay into baryons, were observed conclusively the decays B [yields] [Sigma][sub c][sup 0] and [Sigma][sub c][sup ++]. From about 1500 events corresponding to B [yields] [Lambda][sub c][sup +]X reconstruction of exclusive final states of the form [Lambda][sub c][sup +](n[pi]) was started. A comprehensive investigation of particle identification using both the time-of-flight and dE/dx systems was made. Measurement of pion, kaon and proton identification efficiencies have been made, corresponding to several different selection criteria. Measurements of corresponding pion probabilities to fake kaons nd protons have also been made.
