Abstract: We have studied the response of a lead glass electromagnetic shower detector by using an electron beam of 1 and 2 GeV. We present the results obtained from a study on position resolution of the detector. The stability of the calibration was monitored by using an LED system and an Am-source system. The position resolution varies for clusters with the number of blocks in the cluster. The average resolution is 2cm. The detector was used in a "mock" experiment to reconstruct the $\pi\sp0$ mass by measuring the two photons coming from $\pi\sp0$ decay. We measure a mass of 135.5 $\pm$ 12.5 MeV for the $\pi\sp0$. The actual mass of the $\pi\sp0$ from the particle data booklet is 134.96. The width of the $\pi\sp0$ mass, which is a test of the energy resolution of the detector, gives 18%/$\surd$E.
