摘要：

A method is proposed to calculate the first and second moments of the, spatial distribution of the energy of electromagnetic and hadronic showers measured in laterally segmented calorimeters. The technique uses a logarithmic weighting of the energy fraction observed in the individual detector cells. It is fast and simple requiring no fitting or complicated corrections for the position or angle of incidence. The method is demonstrated with GEANT simulations of a BGO detector array. The position resolution results and the e/pi separation results are found to be equal or superior to those obtained with more complicated techniques.
