  Measurements of branching fractions for nine different final states, based on
a data sample of approximately 4 million psi(2S) events collected with the BESI
detector at the BEPC, are reported. Using the same event sample, radiative
decays of the psi (2S) into pi pi, K K-bar and eta eta final states have been
measured.
  Cross sections for e e -> e e, hadrons, pi pi J/psi, and mu mu have been
measured in the vicinity of the psi(2S) resonance using the BESII detector. The
psi(2S) total width; partial widths to hadrons, pi pi J/psi and muons; and
corresponding branching fractions have been determined.
  Decays of J/psi -> gamma eta_c are used to determine the mass and width of
the eta_c using a sample of 58 M J/psi events. $M_{\eta_c} = (2977.5 \pm 1.0
\pm 1.2)$ MeV and $\Gamma_{\eta_c} = (17.0 \pm 3.7 \pm 7.4)$ MeV.
  The first observation of chicJ (J=0,1,2) decays to lambda lambda-bar is
reported using psi(2S) data collected with the BESII detector. Results are
compared with model predictions.
