Abstract Results from a test with a lead-copper calorimeter in liquid argon are presented. The electromagnetic energy resolution obtained is 10%/√E. For hadronic showers the software weighting technique is demonstrated to work. A hadronic energy resolution of 50%/√E is found.

A lead-copper calorimeter in liquid argon and an iron streamer tube calorimeter acting as a tail catcher have been tested with pions in the energy range of 30–230 GeV. Results are given on the energy resolution, on sampling fluctuations and on the space resolution of the liquid argon calorimeter. For the combined system an energy resolution of σE ≈ 0.5√E is obtained applying software weighting techniques and corrections for the dead material between the two calorimeters on an event to event basis. The remaining tails in the energy distributions are discussed.

The cross section for the processe+e−→π0+ anything has been measured at an average center of mass energy of 34.6 GeV for π0 energies between 0.7 and 17 GeV. The angular distribution for π0 energies larger than 2 GeV is of the formdσ/dΩ∼1+Acos2θ, withA=1.2±0.5. The ratio of π0 to π± production in the measured energy range is 2σ(π0)/(σ(π+)+σ(π−))=1.13±0.18The form of the differential cross sections agrees within the errors. The mean π0 multiplicity is 5.8±0.9.
