On the Penetrating Shower originating in Light Element and Heavy Element

Comparison was made on the penetrating shower originating in carbon and lead. Using the counter hodoscope and the Wilson cloud chamber, the multiplicity of the penetrating shower and the absorption of the shower particle and the secondary event produced by the shower particle were observed. Consequently different energy spectrum at lower energy and its equality at higher energy of the shower particles for different size of the mother nucleus were tentatively concluded and discussed.
