In a Si/U hadron calorimeter, a combination of low-Z and high-Z materials used as absorber enables the reduction of the calorimeter response to the electromagnetic component of the incoming hadronic showers (the local hardening effect). This paper reports that as a result, a ratio varying from e/{pi} {gt} 1 to e/{pi} {lt} 1 is obtained as a function of the low-Z material thickness, demonstrating the possibility of achieving the compensation condition (e/{pi} = 1).
