Abstract:

The energy and spatial resolution in the LGD are measured using 2-shower invariant mass distributions from $\eta \to 2\gamma$ and $\pi^0 \to 2\gamma$ decays. The mass resolution of the $\eta$ is mainly driven by the shower energy resolution while the width of the $\pi ^0$ has a large spatial resolution contribution. Simultaneous analysis of the $\eta$ and $\pi ^0$ data enables extraction of the parameters that describe both the shower energy and spatial resolution of the LGD.
